advanced_menu_toggle / Mobile menu for desktop

Hello there
i use latest Enfold and WPress
i search a lot in your topics but i found only tips for older version
the dev website here : http://dev-afgolf.albatros-solutions.fr/

/ QUESTIONS A /
i customise css to have mobile menu for desktop like this :
@media only screen and (max-width: 4000px) {
nav.main_menu {display:none !important;}
#advanced_menu_toggle, #advanced_menu_hide {display:block !important;}
}
but i can see empty space on desktop where my menu – please see screenshot here

• can you tell me how can i disable it ?
• how can i add some text (MENU) on the right of the burger icon ?
• is it possible to have this icon on the left of the window ?

/ QUESTIONS B /
I want to use a second menu – colored – this one with Ubermenu maybe – below the header on each page of the website – like this

• do you know the best way to get this in Enfold ?
i think i can’t use Enfold secondary menu position for this
the best way is to include Ubermenu shortcode in each page – [ubermenu config_id=”main” menu=”34″]
• in witch element can i put it to have full width menu – like in screenshot ?
• is there a better way to add this in each page ? maybe add php – <?php ubermenu( ‘main’ , array( ‘menu’ => 34 ) ); ?> – in php template ?
