Portfolio is the only custom post-type which has been added in Jupiter X. By using the Raven Posts element, you can display the Blog and Portfolio posts in your Elementor's layout.
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.
In order to display content of the Portfolio post type in your Elementor's layout:
1. Add a new page or edit an existing one.
2. Click on Edit with Elementor button.
3. From the Elementor's left dashboard, drag and drop the Posts widget into your layout so that a new panel will open on the left side of the Elementor with the element's specific settings.
4. From the Content tab and within the Content section set the Source of the posts to Portfolio
5. Update the page.
