I need to publish the desktop menu but i can't find the menu position associated to the template in the dropdown menu of the module settings.
thanks for any help.

i discovered that
<position>menu</position>
was missing into the TemplateDetails.xml and i corrected so now i can publish the main menu correctly.

This theme have no menu position. It has has only a offcanvas menu position

I'm sorry but i disagree.
Inserting the new menu position let me recreate exactly the demo with the menu on the left side above the top-a postio as mentioned into the documentation (into the module postion map the menu position is there). Now my website works fine with the menu always on the top even when i'm scrolling the page down.
