In the Bricks Facebook group a user asks:
Data Attribute as a Condition
Is it possible to place a data attribute as an element condition, if yes, how?
Before Bricks added the ability to set conditions on elements in the editor, we’d use bricks/element/render filter for the conditional output.
This Pro tutorial shows how this filter can be used to not render elements that have a specific data attribute with a name of data-dont-output set.

On the front end:

Add the following in child theme‘s functions.php (w/o the opening PHP tag) or a code snippets plugin:
<?php
add_filter('bricks/element/render', function($render, $element) {
// Check if the element has attributes set
if ( isset( $element->settings['_attributes'] ) && is_array( $element->settings['_attributes'] ) ) {
// Loop through the attributes
foreach ( $element->settings['_attributes'] as $attribute ) {
// Check if the attribute name is 'data-dont-output'
if ( isset( $attribute['name'] ) && $attribute['name'] === 'data-dont-output' ) {
// If found, return false to prevent rendering
return false;
}
}
}
// If the attribute is not found, return the original render value
return $render;
}, 10, 2);
