Description

This JavaScript filter allows you to modify the CSS class applied to the Expanded Editor modal overlay in ACF Blocks V3. This is useful for applying custom styling to the overlay.

Parameters

acf.addFilter( 'blocks/expanded_editor_overlay_class', function( className, block ) {
    return className;
});

Example

    return className + ' my-custom-overlay';
});

Apply different classes based on block name

acf.addFilter( 'blocks/expanded_editor_overlay_class', function( className, block ) {
    if ( block.name === 'acf/hero' ) {
        return className + ' hero-overlay';
    }
    return className;
});

Replace the class entirely

acf.addFilter( 'blocks/expanded_editor_overlay_class', function( className, block ) {
    return 'my-overlay-class';
});
