# Date/time picker element (mobile) Lets users select a date, a time, or both. On native mobile, it uses the device's built-in picker interface, ensuring a familiar experience that follows the platform's design patterns and accessibility standards. The selected value is stored as a full date-time, even if only the date or time is shown. ## Visual ### Content #### Input type Sets which value the element should collect. * **Date:** Opens the device's native date picker. On iOS, this typically appears as a wheel-style picker or calendar depending on system settings. On Android, it appears as the system date dialog. * **Time:** Opens the device's native time picker. On iOS, this is usually a wheel-style time selector. On Android, it appears as the system time dialog (clock or numeric input, depending on version). #### Placeholder Sets a date as the placeholder for the date/time picker. Note that the placeholder does not return any value — it is purely visual. #### Initial content Sets the default date/time. {% hint style="info" %} When you save only a date, the time is set to 12:00 AM (midnight) in the database, based on the user's time zone. Because Bubble stores dates in Unix format[^1], every value always includes both a date and a time, even if time selection is disabled in the input element. You can read more about how Bubble handles dates and time in [Time, dates and time zones](https://manual.bubble.io/help-guides/data/time-dates-and-time-zones). {% endhint %} ### Size Sets the width and height of the element. These properties depend on the layout configuration of the parent element. **Height** Sets the width/height of the element. The column, row and align layouts have a more flexible way to set element position.

Type	Description
Fixed	Sets the width of an element as a fixed pixel value.

### Layout #### Alignment #### Parent layout: Column In a column layout, a child element's property is restricted to the vertical axis.

Alignment	Description
Left	Elements are aligned to the left edge.
Center	Elements are aligned to the vertical center of the container.
Right	Elements are aligned to the right edge.

#### Parent layout: Row In a row layout, a child element's alignment property is restricted to the horizontal axis.

Alignment	Description
Top	Elements are aligned to the top edge of the container
Center	Elements are aligned to the horizontal center of the container.
Bottom	Elements are aligned to the bottom edge of the container.

#### Parent layout: Align In an align layout, a child element's property is restricted to one of nine cells in a 3x3 grid. Any element placed within the same cell will overlap.

Alignment	Description
Top-left	Elements are aligned to the top-left corner of the container.
Top-center	Elements are aligned to the top edge and horizontally centered within the container.
Top-right	Elements are aligned to the top-right corner of the container.

#### Parent layout: Fixed Elements are positioned using fixed X and Y coordinates, defined in pixels. #### Spacing #### Padding Defines the internal spacing between an element’s content and its border in a static pixel value. Padding adds space inside the element, without affecting its position relative to other elements. Padding is added on the vertical and horizontal axis respectively. #### Margin Defines the external spacing between an element and surrounding elements. Margin adds space outside the element’s border. It affects the distance between elements and influences layout positioning. ### Configure #### Style Defines how the date/time picker is displayed. *Label and icon* shows a label alongside the picker trigger. *Label* displays text only, without an icon. #### Icon Sets the icon displayed on the date/time picker, if *Style* is set to *Label and icon*. #### Accent color Sets the highlight color used in the native picker interface, where supported by the platform. You can adjust both the color and its opacity. #### Clock type Determines the time format used in the picker. *12 hour* displays time with AM/PM. *24 hour* displays time using a 24-hour format. #### Date constraints Limits the selectable date range. You can define a start date and end date, either as static values or dynamic expressions. Users can only select dates within the specified range. ### Style Style sets the visual design of the element, including properties such as colors, fonts, borders, shadows and other appearance settings. Styles are shared across elements. When multiple elements use the same style, updating the style will automatically update all elements that reference it. #### Style selector

Select the style to apply to the selected element. #### Edit style

To edit the style, click the edit style icon. The changes to that style will apply to all elements using that style. #### **Detach style** Detaching the style will disconnect the element from the current style, but keep the formatting of the style until you make changes to it. This only affects the selected element.

#### **Overriden styles** You can override a style on one or more elements, using the defined style properties but allowing you to make individual changes to styling properties that apply only to the selected element(s). Overridden styles will be marked with an *Overridden labelI.*

You can reset the selected element's style by clicking the *Reset* icon.

### Appearance The appearance section lets you control the opacity, rotation and radius (corner roundness) of the selected element(s). #### Opacity Opacity sets the transparency level of the selected element(s). At 100%, the element is fully opaque. At 0%, it is fully transparent (invisible).
* **Opacity affects child elements**: If applied to a container, all child elements inherit the same opacity level. * **Opacity does not collapse the element:** Even at 0%, the element still occupies space in the layout. Unlike hiding an element (using *This element is visible on page load*, a conditional visibility rule, or a hide/show action), opacity does not reduce the element’s width or height to zero. #### Radius Sets the roundness of the selected element(s).

How radius is calculated

The value is applied in pixels and determines the radius of the corner’s arc. Larger values create more rounded corners. The maximum visible roundness depends on the element’s size. If the radius is set to a value greater than half of the element’s width or height, the browser automatically caps it at half of the smallest dimension. For example: * A square (100 × 100 px) with a radius of 50 px becomes a circle. * A rectangle (200 × 100 px) with a radius of 50 px becomes a pill shape. * Setting a radius larger than 50 px in the second example will not increase the curvature further, because 50 px is already half of the element’s height.

**Individual radius** To set an individual radius of each of the four corners, click the Individual radius icon.

### Border The border defines the outline of the selected element. It is drawn around the element’s content and padding. Increasing the border width increases the total visible size of the element unless the layout system compensates for it. Borders sit outside the padding but inside the margin. Padding adds space between the content and the border, while margin adds space outside the border, affecting the distance to neighboring elements.

Border types

{% hint style="info" %} **Note:** some of these border types require a width of more than 1 pixel to make a visible difference. {% endhint %}

Border type	Description
None	No border is displayed.
Solid	A single continuous line.
Dotted	A series of round dots forming the border line.
Dashed	A series of short line segments forming the border.
Double	Two parallel solid lines. The total border width is divided between the two lines and the space between them.
Groove	A carved effect that makes the border appear pressed into the page, using light and dark shading.
Ridge	The opposite of groove; creates a raised effect using light and dark shading.
Inset	Makes the element appear embedded into the page, with shading that simulates depth inward.
Outset	Makes the element appear raised from the page, with shading that simulates depth outward.

#### **Border width** Sets the width of the border, defined by a pixel value. #### **Border color** Sets the color of the border in a hex value. You can also set the opacity of the border. Can be a static or the result of a dynamic expression. #### **Individual borders** To set individual border properties on the top, bottom, left and right, clitk the individual border icon.

### Background Sets the background of the selected element(s) as a color, gradient or image. #### Color Sets the background color in a hex value. You can also set the opacity of the border. Can be a static or the result of a dynamic expression. #### Gradient Sets a gradient color, ranging from a start color and an end color, with an optional mid color.

Linear gradient

A linear gradient is a background effect where colors transition gradually along a straight line. The gradient follows a defined direction (for example, top to bottom, left to right, or at a specific angle). Instead of a single solid color, the element displays a smooth blend between two or more colors across that line.

Starting point	Description
Top	The gradient begins at the top and transitions downward.
Left	The gradient begins on the left side and transitions horizontally to the right.
Bottom	The gradient begins at the bottom and transitions upward.
Right	The gradient begins on the right side and transitions horizontally to the left.
Custom	Allows you to define a specific angle for the gradient direction.

Radial gradient

A radial gradient is a background effect where colors transition outward from a central point. Instead of following a straight line (like a linear gradient), the color spreads in a circular or elliptical shape from the center to the edges. #### Radial gradient types

Type	Description
Circle	The gradient expands evenly in all directions from the center, forming a perfect circle.
Ellipse	The gradient expands in an oval shape, stretching more in one direction based on the element’s width and height.

#### Radial gradient expansion Define how far the radial gradient extends from its center point. They control which edge or corner of the element determines the gradient’s final size, affecting how quickly the color transition spreads across the element.

| Option | Description | | --------------- | ----------------------------------------------------------------------------------------- | | Closest side | The gradient expands from the center until it reaches the nearest side of the element. | | Closest corner | The gradient expands from the center until it reaches the nearest corner of the element. | | Farthest side | The gradient expands from the center until it reaches the farthest side of the element. | | Farthest corner | The gradient expands from the center until it reaches the farthest corner of the element. | #### Stops Sets the start and end point of the radial gradient. By default, it has a *Start* and *End.* Optionally, you can add an intermediate point by clicking the + symbol next to *Stops.*

#### Image Sets an image as the element's background. The image can be a static file uploaded directly in the editor, or the result of a dynamic expression. **Upload** Upload a static image file to use as the background. **Make dynamic** Click the + icon to define a dynamic expression that returns the image to use as the background. ### Text Sets the typography of the selected element(s). Only applies to elements that contain text. #### Font Sets the font family used for the text. You can choose a custom font or use a saved font variable. #### Font weight Sets the thickness of the text. Lower values (for example, 400) are lighter, while higher values (for example, 600 or 700) appear bolder.

Understanding font weight

Font weight is not calculated mathematically. It’s defined by the font itself. Most modern fonts use a numeric weight scale from 100 to 900: * **100–300:** lighter weights * **400:** regular (normal) * **500–600:** medium / semi-bold * **700:** bold * **800–900:** extra bold / black However, available weights differ between fonts. One font might include 400, 600, and 700, while another only includes 400 and 700. A weight of 700 in one font is also not guaranteed to look the same as 700 in another font. The numeric scale (100–900) is standardized in CSS, but each font designer defines how thick “700” actually appears within that typeface.

#### Font size Defines the size of the text in pixels. #### Text alignment Controls how text is aligned within the element: left, center, or right. #### Text formatting Applies inline formatting options such as bold, italic, and underline. Click the *More properties* icon for more formatting options.

Additional text properties

**Word spacing** Defines the horizontal space between words. Increasing the value spreads words further apart; decreasing it brings them closer together. **Line spacing** Controls the vertical distance between lines of text (line height). Higher values improve readability for longer text blocks, while lower values create a more compact layout. **Letter spacing** Adjusts the horizontal space between individual characters. Positive values increase spacing (tracking), while negative values tighten the text. **Text alignment (vertical)** Controls how text is aligned vertically within its container (for example, aligned to the top or bottom when vertical alignment is enabled). **Text shadow** Adds a shadow effect behind the text. You can configure properties such as offset, blur, and color to create depth or improve contrast against the background.

#### Text color Sets the color of the text. You can select a custom color or use a saved color variable. ### Icon This section is only visible when the date/time picker's [style](#style) is set to *Label and icon.* #### Size Sets the size of the icon as a pixel value. #### Color Sets the color of the icon, and the opacity of the color. #### Trailing/leading Sets the icons position as right (trailing) or left (leading) of the label. ### Shadow Adds an outside or inside shadow to the selected element(s). #### Shadow type Defines whether the shadow appears outside or inside the element. * **Outside:** creates a drop shadow around the element. * **Inside:** creates an inner shadow within the element’s boundaries. #### Position (X / Y) Sets the horizontal (X) and vertical (Y) offset of the shadow in pixels. * Positive X moves the shadow to the right; negative X moves it to the left. * Positive Y moves the shadow downward; negative Y moves it upward. #### Blur Controls how soft the shadow appears. Higher values create a more diffused shadow; lower values produce a sharper edge. #### Spread Defines how much the shadow expands or contracts before blur is applied. Positive values increase the shadow’s size; negative values reduce it. #### Color Sets the shadow’s color and opacity. You can define a custom color (for example, a hex value) and adjust its transparency percentage. ## Interaction ### Workflows Shows the workflows connected to the selected element. Click the + symbol to create a new workflow associated with that element. The list of available events differs based on which element is selected. {% hint style="info" icon="keyboard" %} **Shortcut:** To quickly add a workflow to a selected element, press Cmd+K on macOS or Ctrl+K on Windows. The shortcut defaults to the most likely event for that element type. {% endhint %} ### Visibility #### Visible on view load Enable this to make the element [visible by default](#user-content-fn-2)[^2]. This checkbox makes the element visible every time the view loads. Change the visibility of the element based on certain conditions[^3] in the Conditional section in the property editor or with a show/hide element action[^4] in a workflow. #### Collapse when hidden Enable this to make the element collapse its height and width to 0 pixels when hidden. This allows surrounding elements to automatically shift into the freed space, preventing empty gaps in the layout. This is commonly used in single-page applications, where elements are shown and hidden dynamically as users navigate, without leaving the page. ### Options #### Make required When enabled, the user can't trigger any workflows tied to the date/time picker if a date or time hasn't been selected. #### Make disabled Disables the date/time picker so the user can't interact with it. ### Transitions Transitions add animation when a style property changes. Instead of updating instantly, the element gradually shifts from its previous state to the new one over a defined duration. For example, if you reduce an element’s width, a transition can make it smoothly shrink rather than change size immediately.

Transition styles

Transition style	Description
ease	Starts slowly, speeds up in the middle, and slows down at the end.
ease-in	Starts slowly and accelerates toward the end.
ease-out	Starts quickly and decelerates toward the end.
ease-in-out	Starts slowly, accelerates in the middle, and slows down again at the end.
linear	Moves at a constant speed from start to finish.
step-start	Jumps immediately to the end state at the start of the transition.
step-end	Remains in the start state and jumps to the end state at the very end of the transition.

#### Transition duration Transition duration defines how long the transition animation runs, measured in milliseconds. ### Advanced #### Time zone selection {% hint style="info" %} This property requires that you check the *Enable timezone override controls* and *Date-time inputs (Date-Time Picker and Input)* checkboxes under *Settings – General*. {% endhint %} Determines which time zone the date/time picker uses. By default, it uses the user's local time zone as defined by their browser. Switching to *Static choice* reveals an additional property: * **Time zone ID:** lets you select a specific time zone from the full list of global time zones. {% hint style="info" %} You can also define the time zone at the page level. Enable *Timezone override* on the page, then check the *Page* option to set a specific time zone ID. When configured, all date/time elements on the page use the same time zone, ensuring consistent display and behavior. {% endhint %} [^1]: *Unix format* stores a date and time as a single number representing the number of seconds (or milliseconds) since January 1, 1970 (UTC). [^2]: Visible by default means that the element is visible when you load/reload the page. [^3]: *Conditions* are appliead to elements to make them change their apperance or behavior based on a specific condition. Conditions are built using dynamic expressions.
