Query Elements is an extension to Elementor that adds new WP_query related widgets to Elementor. The Archive and Posts widget fully implement the WP_Query method. No need to hook in to any filters or work in the backend. Archives, archive paging, single paging and more is supported.
Display Conditions is a free basic add-on to Elementor that gives you the ability to decide if a Section widget/element should be display or not according to some conditions that you setup. I made this for this site since I needed to hide a section on pages where an ACF video field was empty. It requires PHP 7.1 or above.
The ACF Icons plugin adds a new field to Advanced Custom fields. It gives you the ability to use a new field type ‘Icon’. It also works with repeater fields. Out of the box it supports Font Awesome 5 and Ionicons. If you have Elementor plugin you can select Elementor icons as well.
