Filter: bricks/elements/{element_name}/control_groups

Since Bricks 1.4 it is possible to add custom control groups to a specific element like so:

add_filter( 'bricks/elements/heading/control_groups', function( $control_groups ) {
    $control_groups['custom_controls'] = [
        'tab'      => 'content', // or 'style'
        'title'    => esc_html__( 'Custom controls', 'my_plugin' ),
    ];

    return $control_groups;
} );

Note: the above example adds a new control group with the title “Custom controls” to the heading element, using the filter bricks/elements/**heading**/control_groups. To learn about other Bricks controls, visit the Controls section.
