[GELÖST] Full screen menu/mega menu

Hi !
is it possible to make a full screen menu like in the picture ?
template tp_golf , Joomla 4.4.2
thanks for your advices

I'm sorry but I don't understand what you mean.
Please explain exactly what you want to do and what it should look like.
The picture says little.
Always provide URL for design questions.

thank you for your quick response
the easiest way is indeed to send a link to an example :
esterelcotedazur-agglo.fr/promenade-des-...-enquetes-publiques/

If I understand correctly, you want to display the currently existing offcanvas menu (Right Hamburger) as the main menu in the header?
Or should the menu always be displayed completely on every page like a header?

the first solution would be satisfactory
we just keep the sticky header with the hamburger menu button (and other info: logo, phone, etc.)

Thanks for putting me on the trail...
I found a solution with the hamburger menu
Regards !
