I would like to insert a sticker on one side of the screen (in a different position if for desktop or smartphone) to associate a specific side menu.
In "Navigation" there is an option "Enable Offcanvas" but it is reserved for displaying the main menu.
So I was wondering if it's possible to manage what I have in mind to do in another way; for example using something already available in Joomlart (template or extension) or a change to the CSS.
Thanks in advance for any advice.
