mobile menu sticky

Hello and thank you for your great template.
I would like some help with makinh the mobile menu sticky.
I have set it up correnctly (both logo-small mobile and offcanvas menu) but what i want is the mobile menu (with the logo small or alone i don't care) to be sticky just like the menu in the big screens (i have put it in fixed navigation).
Thank you!

Hi there,
sorry thats not possible, because only one menu can be sticky.
And the only one menu is the main menu.

If you want that the mobile is sticky you have to change the > layouts/theme.php and customize it.
