The Unlimited Elements for Elementor plugin is an addon package with a twist. It comes with more than 200 widgets, but it also comes with a “Widget Creator.” The Widget Creator provides an interface for adding your own customize widgets. You can create your own or start with their library of more than 700 jQuery scripts already added and customize those. This requires some coding ability, but allows you to create your own interactive elements and extend Elementor in new ways. There is support for Advanced Custom Fields. The plugin is available for 1, 5 or unlimited websites.
