Tab bar element

The tab bar is a container that rests at the bottom of the screen and contains tab items. It's not added from the element pallette, but instead appears when the current view has Include as tab item or Show tab bar enabled in the Configure - Navigation property.

You can't add elements directly to the tab bar container. Each view that has Include as tab item will be listed as a tab item that can be configured.

Visual

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	Options
Fixed	Sets the width of the element as a fixed value.	Pixels: sets the width to a fixed pixel value Percentage: sets the width to a percentage of the parent container
Fit	The element’s width and height automatically adjust based on the size of its child elements. To add a mininum and/or maximum value, click the + symbol.	Min: the minimum width/height, defined as a pixel value or percentage of the parent container. Max: the maximum width/height, defined as a pixel value or percentage of the container.
Fill	The element's width and height fills the available space in the parent container. To add a mininum and/or maximum value, click the + symbol.	Min: the minimum width/height, defined as a pixel value or percentage of the parent container. Max: the maximum width/height, defined as a pixel value or percentage of the container.

Parent container has a fixed layout

Width/height

Sets the widht/height of the element. The fixed layout has a more rigid way of setting element size, based on static pixel values.

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

Layout

Alignment

This setting applies to column/row layouts.

Column and row layouts support different alignment modes that control how child elements are positioned along the main and cross axes.

Left (start)

Aligns child elements to the start of the container.

• In a column layout, elements align to the top.

• In a row layout, elements align to the left.

Center

Aligns child elements to the center of the container along the relevant axis.

• In a column layout, elements are centered horizontally.

• In a row layout, elements are centered vertically.

Right (end)

Aligns child elements to the end of the container.

• In a column layout, elements align to the bottom.

• In a row layout, elements align to the right.

Space between

Distributes child elements evenly, with equal space between them and no extra space at the edges of the container.

Space around

Distributes child elements evenly, with equal space around each element. This results in half-sized spacing at the container’s edges compared to the space between elements.

Spacing

Gap (column and row layout)

Defines the space between child elements inside a container.

The gap is applied between items in a column or row layout. It does not add space before the first element or after the last element — only between siblings.

• In a column layout, the gap controls vertical spacing.

• In a row layout, it controls horizontal spacing.

If child elements also have margins, the gap and margin values are cumulative. For example, a container with a 10 px gap and a child element with a 10 px margin between items will result in 20 px of total space between those elements.

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.

Tab items

Lists the tab items available in the tab bar. You can add views as tab items by clicking the + icon.

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

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

Note: some of these border types require a width of more than 1 pixel to make a visible difference.

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.

Generating an image with AI

You can generate images with AI. Type in a prompt and select a size, quality, and style. The Auto setting lets the AI choose based on your prompt. The number of tokens used depends on your selections.

Check Generate Alt tags to automatically generate an Alt text.

Make dynamic

Click the + icon to define a dynamic expression that returns the image to use as the background.

Interaction

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

A unique identifier assigned to the element. This can be used to reference the element in custom code, such as JavaScript or CSS, using document.getElementById() or CSS selectors.

For this property to be visible, you need to enable Expose the option to add an ID attribute to HTML elements in Settings – Advanced options.
