I found out how to do this. Add your code where needed in your template files and add display:none; in your css. Then, in the media queries of your choice, put display:block; to make it appear.

My example :

<nav id=”selectmenu”>
<?php dropdown_menu( array( ‘menu’ => ‘Main’ ) ); ?>
<?php dropdown_menu( array( ‘menu’ => ‘Groupeage’ ) ); ?>
<?php dropdown_menu( array( ‘menu’ => ‘Evenements’ ) ); ?>
</nav>

my css :

#selectmenu {
display:none;
}

@media only screen and (max-width:600px) {

#selectmenu {
display:block;
}

}

just make sure to display:none; your other menu if necessary
