Using Gravity Forms ‘gform_editor_sidebar_panels’ PHP action

The gform_editor_sidebar_panels filter enables custom panels to be registered for display in the form editor sidebar.


To run the filter for all forms:

add_filter('gform_editor_sidebar_panels', 'your_function_name', 10, 2);

To target a specific form, add the form ID after the hook name:

add_filter('gform_editor_sidebar_panels_6', 'your_function_name', 10, 2);


  • $panels (array) – An array of custom sidebar panels.
  • $form (Form Object) – The form currently being edited.

add_filter('gform_editor_sidebar_panels', function ($panels, $form) {
    $panels[] = array(
        // Define the unique ID for your panel.
        'id'          => 'my_custom_panel_1',
        // Define the title to be displayed on the toggle button your panel.
        'title'       => 'My Custom Panel',
        // Define an array of classes to be added to the toggle button for your panel.
        'nav_classes' => array('my_nav_class_1', 'my_nav_class_2'),
        // Define an array of classes to be added to the body of your panel.
        'body_classes' => array('my_body_class_1'),

    return $panels;
}, 10, 2);
