Fires on the Form Editor page after a field’s settings panel has been opened and settings have been displayed.


<script type="text/javascript">
    jQuery(document).on('gform_load_field_settings', function(event, field) {
        // custom JS code here



This hook is primarily used in conjunction with the gform_field_standard_settings, gform_field_advanced_settings, and gform_editor_js hooks.

The gform_field_standard_settings and gform_field_advanced_settings hooks are responsible for displaying custom field setting UI. These hooks are typically used in conjunction with the gform_editor_js hook to output any JS required by the custom settings UI. As part of this process, the gform_load_field_settings JS hook can be used in the gform_editor_js PHP hook, to only perform certain actions once the field settings have loaded.
