For information I trying something like this : [mb_frontend_dashboard edit_page="158" columns="title" post_type="realeaste-list"], because I thought the shortcode nned to know the post type to display good info, but same!!
I just find the solution its because :
You need to add the attribute post_type to the frontend submission shortcode
[mb_frontend_form id="meta-box-id" post_fields="title,content" post_type="post-type-slug"]
but that is explain into the FAQ drowdown menu....!!! arrrg
That will be cool that the staff create a Widget for elementor to automize all that!
