Question: WordPress does't give `ul.sub-menu` any unique classes (yet)...

Here is my HTML:

```
<ul id="menu-primary" class="nav">
 <li>News
   <ul class="sub-menu">
    <li>Local</li>
    <li>Politics</li>
   </ul>
 </li>
 <li>Sports
   <ul class="sub-menu">
    <li>Baseball</li>
    <li>Football</li>
   </ul>
 </li>
 <li>Opinion
   <ul class="sub-menu">
    <li>Forums</li>
    <li>Blogs</li>
   </ul>
 </li>

```

Using jQuery I can .addClass to the first one only.

```
 jQuery(document).ready(function($){

     $('ul.sub-menu').addClass (function() {
         return "item-" + $(this).index();
});

```

The result is this:

```
<ul id="menu-primary" class="nav">
 <li>News
   <ul class="sub-menu item-1">
    <li>Local</li>
    <li>Politics</li>
   </ul>
 </li>
 <li>Sports
   <ul class="sub-menu">
    <li>Baseball</li>
    <li>Football</li>
   </ul>
 </li>
 <li>Opinion
   <ul class="sub-menu">
    <li>Forums</li>
    <li>Blogs</li>
   </ul>
 </li>

```

That's great, but **how do I assign a unique class to EACH** `ul.sub-menu`?

Answer: 
try this code, should do the work.

```
$(function(){        
     $('ul.sub-menu').addClass (function(idx) {         
         return "item-" + idx;
     });
 });

```

Haven't tested it.. but .each() would be the function you need.

```
$('ul.sub-menu').each(function(index) {
    $(this).addClass("item-" + index);
});

```
