Select ul element with same class inside ul element

Question

How select second ul element with "dropdown-menu" class inside ul element with same class?

<ul class=" dropdown-menu">
<li>
<ul class=" dropdown-menu">
</ul>
</li>
</ul>

Answer 1

If you want to select just the 2nd element, here is the workaround:

CSS

.dropdown-menu .dropdown-menu:first-child {}

More specific version:

ul.dropdown-menu li ul.dropdown-menu:first-child {}

jQuery

$('.dropdown').find('.dropdown:first').addClass('child-dropdown-menu');

Cheers!

Here's a pure js answer I'm assuming you already have the ul reference in a variable.

var uls = ul.getElementsByTagName("ul");
var targetUl = undefined;

for(var i = 0; i < uls.length; i++){
    for( var j = 0; j < uls[i].classList.length; j++){
        if(uls[i].classList[j] == "dropdown-menu"){
            targetUl = uls[i];
            break;
        }
    }
}
