Conditional Formatting

Conditions

You can control how page elements behave and appear under certain circumstances. Define these conditions and the properties to be altered in the Conditional Formatting section in the Property Editor. States are applied in the order listed. If two states are active and modify the same property, the state listed last is the one used.

Note: With conditionals, you can create your own input validation, e.g. "This button should not be clickable until the input is at least 3 characters long". Some of these validations are not evaluated on each keystroke, but rather after the user pauses for a second.

When

A condition defines when the properties should change. A condition can be about the element itself, e.g., when a button is hovered or clicked or be based on a more complex expression, such as when the user is logged in. Build this expression one condition at a time. As this condition should return yes or no, it will be red until the condition is valid.

Select a property to change when true

Select which properties to modify from this dropdown menu when the element meets the condition.

Move up

Clicking this button moves the condition up by one. The condition originally above the current condition will be moved down one.

Move down

Clicking this moves the condition down by one. The condition originally below the current condition will be moved up by one.

Remove condition

Clicking this removes the condition from the current element.

On/Off

This button turns the condition on or off in the editor, so that you can preview what different states of the condition look like. The default is off. For more information:

Can have the slug value [Beta]

This operation tests if the argument is a valid slug value for the Thing. A valid slug value is both unique and correctly formatted with only lowercase letters, digits, and hyphens.

Cannot have the slug value [Beta]

This operation tests if the argument is an invalid slug value for the Thing. An invalid slug value is anything that isn’t made up of only lowercase letters, digits, and hyphens or that is not unique.

Transitions

For a smoother effect, transitions change an element's properties over time. For example, define a transition so the background color changes over 500 milliseconds. When the color changes, the element's color will change gradually over 500 milliseconds instead of at one time.

Note: Transitions are not applied to gradient backgrounds.

Duration

Length of the transition in milliseconds.

Transition timing dropdown

This parameter determines how the intermediate values of the transition are calculated. Choose from several curves.

Select a property to define a new transition

From the dropdown menu, select the property to apply the transition to.

Remove the transition

Click the trash icon to remove the transition. The property will change instantaneously instead of gradually.
