The “gform_rich_text_editor_buttons” filter in Gravity Forms controls the buttons displayed in the first row within the Gravity Forms rich text editor. This hook may be filtered by FORMID or by FORMID + FIELDID.


Applies to all forms:

add_filter( 'gform_rich_text_editor_buttons', 'my_function', 10, 2 );

To target a specific form append the form id to the hook name. (format: gform_rich_text_editor_buttons_FORMID)

add_filter( 'gform_rich_text_editor_buttons_2', 'my_function', 10, 2 );

To target a specific form field append the form id and field id to the hook name. (format: gform_rich_text_editor_buttons_FORMID_FIELDID)

add_filter( 'gform_rich_text_editor_buttons_2_6', 'my_function', 10, 2 );


  • $mce_buttons array

    Array of buttons to include within the TinyMCE editor inside Gravity Forms.

array( 'formatselect', 'bold', 'italic', 'bullist', 'numlist', 'blockquote', 'alignleft', 'aligncenter', 'alignright', 'link', 'unlink', 'spellchecker' );

Note: Spell Checker button was removed from WP core since version 3.6; you need to install a third-party plugin if you want to use it, e.g. TinyMCE Spellcheck.

  • $editor_id string

    The HTML element ID for the field using the rich text editor.

  • $field_object object

    Object containing information about the field.


This example shows how you can add another button.

add_filter( 'gform_rich_text_editor_buttons', 'my_function', 10, 2 );
function my_function( $mce_buttons ) {
    $mce_buttons[] = 'wp_more';
    return $mce_buttons;

This example shows how you can remove the majority of the buttons.

add_filter( 'gform_rich_text_editor_buttons', 'my_function', 10, 2 );
function my_function( $mce_buttons ) {
    $mce_buttons = array( 'bold', 'italic', 'bullist' );
    return $mce_buttons;

The following will apply for all fields with the rich text editor enabled in a form with id 2.

add_filter( 'gform_rich_text_editor_buttons_2', 'my_function', 10, 2 );
function my_function() {
    $mce_buttons = array( 'bold', 'italic', 'bullist' ); // Enable only Bold, Italic and Bullet List buttons
    return $mce_buttons;

Filtering additional button rows

Gravity Forms also makes filters available to control the display of buttons in rows two through four of the rich text editor:

These filters can be used in the exact same way as the usage examples for the gform_rich_text_editor_buttons filter above but they allow you to filter additional rows in the rich text editor. Which row is filtered is noted in the filter name.

By default WordPress includes buttons in the first and second row of the TinyMCE editor, but other components in your site’s setup could include buttons in the third and fourth row including via these filters.
