PowerPack Formidable Forms styler widget allows you to style and customize the native forms created using the Formidable Forms plugin.
If you’re using the PowerPack form styler widget and unable to see in the Elementor editor, make sure you’ve installed and activated:
You can check all the activated in your WordPress Dashboard >> Plugins >> Installed Plugins.
Next, make sure you’ve enabled Formidable Forms Styler widget in PowerPack Widget settings. To find this option, click Elementor >> PowerPack >> Elements.
In the Elements page, find the Formidable Forms and enable the toggle to use the styler in the Elementor editor.
Hope this helps!
