You can create templates in elementor (a section). Using Templates > Section > add new.
Then in the templates list view you can copy the shortcode of the template and use that in the tabs widget.
You can check out this YT tutorial to see the steps: https://www.youtube.com/watch?v=RgJYtcfDHQg
Thanks for your reply.
There is still something that i dont get yet.
How do i add the listings blocks that i create on the back end, to the front page in the blocks?
For example, how do i add a tab of the reviews of the listing? There is a place that i can find the shortcodes?
I Really hope i can do it with the plug-in and then i will buy the pro version.
If you have the free version, you cannot add a reviews block.
If you have the PRO version, the pro version includes a lot of elementor widgets like review list, review form, business hours, related listing and many more.
