Block Condition

Affects a block's visibility based on a condition expression.

Configuration

Select the block you want to apply the visibility condition to.
Click on the Block Condition button in the editor's toolbar and a configuration window will appear.
Use the Select parent element button to choose the parent of the currently selected block. Specify the condition expression and confirm.

Test (expression)

Define a simple field name or formula using the expression language that evaluates to a boolean value.
If the result is true, the block will be visible; otherwise, it will be hidden.

Examples:
Surname – evaluates to true if Surname is populated
quantity > 0 – hides the block when quantity is less than or equal to 0

Type Conversion Table

When your expression doesn't return a boolean type natively, other types are converted to boolean based on the following rules:

Evaluates to true if...

• Number - The value is not 0
• String - The value is populated (non-empty)
• Array - The array is not empty
