Control not appearing in the panel?

If your Elementor custom controls are completely missing from the editor sidebar, first ensure that the elementor/controls/register action hook is firing. Double-check your plugin is activated. If the hook is firing, verify that the get_type() string in your PHP class perfectly matches the type parameter you used inside the widget's add_control() method.

JavaScript errors in the console?

When Elementor custom controls fail to load interactively, open your browser's Developer Tools (F12) and check the Console tab. If you see errors regarding elementor.addControlView is not a function or BaseData is undefined, your JavaScript file might be enqueued too early. Ensure your script is enqueued on the elementor/editor/after_enqueue_scripts hook and has jquery as a dependency.

Value not saving on update?

If you can interact with your Elementor custom controls, but the page doesn't update or the value reverts upon saving, the JavaScript view is failing to bind data. Check your Marionette.js events object. Ensure you are calling this.setValue( newValue ) when the user interacts with the UI. Furthermore, guarantee your HTML template includes an element, as Elementor relies on this data attribute to extract the model value.
