[SOLVED] Adapting the template to mobiles ?

Hello
My site with your template X2 is on line, but how can I adapt it to the mobiles ?
Mainly :
- unpublish the widgetkit images in the background (for me, video in homepage, and a photo for the other pages).
- display a mainmenu usable on a mobile phone.

What do you mean, please more details!

Sorry, I thought it was clear .
In the admin of some templates we have the possibility to select the behaviour of each part of the site, depending on the size of the screen used : normal computers, tablets, or mobile phones. Not only the responsive function, but which elements must be displayed on which screen.

To display correctly my new website with X2 / Joomla 3 on the mobiles, I would like to :
- disable the images in the background (Widgetkit),
- disable a few modules
- display a mainmenu usable on a mobile phone.

You have the option to disable some modules in mobile devices, therefore you can add a module class suffix to the module.
Disable the module at Tablets ( max width 768px)
module class suffix = hidden-tablet
Disable the module at Phone ( max width 460px)
module class suffix = hidden-phone

OK. Thanks.
It works for standart modules, but, on my phone :
- There is no more mainmenu (without hidden-tablet or hidden-tablet)
- The module Googlemaps, in the position "map", is still displayed (with hidden-tablet &hidden-phone for this module)

Yes youre right, the module class suffix is working only for standard modules and not for menu modules.
The map must be disabled directly with hard coded:

< iframe class="hidden-phone"....
