The Posts element allows you to display posts from Blog or Portfolio post type. It also offers many features like changing posts number and pagination.
Beware! The Posts element is a part of the Raven elements. Raven is an exclusive plugin developed by Artbees which represents new useful elements to Elementor. In order to see the default Elementor Posts, you need to look for it in the Elementor knowledgebase.
