Hello, after importing the Demo of theme, the properties doesn't have an editor, once we click on edit the classic editor opens, we get an HTML Code for the whole page which is pain to deal with .. is this how the theme was made? or it has an editor ? or maybe possible to edit with elementor?
Please go to Elementor/ Setting/ General tab/ and check to Properties and Footer to enable the Elementor page builder for the Properties Custom post type. Then you can use the Page builder to build your content.
