drop-downs dont work on mobile browsers

[collabet]

This skin is simply brilliant! Love it.
Only drawback I encountered so far: drop-downs dont work on mobiles. Neither Android build-in browser, nor Chrome or Firefox (which isnt supported by bootstrap anyway) does open the menus, they highlight only.
Some research clued me that it's a bootstrap prob, considered fixed in later versions.
Strapping uses v2.3.2 for which I found a fix (1), but dunno what to do with it.

jQuery(document).ready(function($) {
$("li.dropdown a").click(function(e){
$(this).next('ul.dropdown-menu').css("display", "block");
e.stopPropagation();
});
});

Feeding that somehow into strapping.js just leaves drop-downs open on desktop and doesnt do anything on mobiles.
Any hint or help is appreciated.
