I am trying to hide items (li?) in a quick launch menu, where it says 'Benefits HIDDEN', the HTML is;

```
<div class=" noindex ms-core-listMenu-verticalBox" id="zz13_idPDPQuickLaunch">
    <ul class="root ms-core-listMenu-root static" id="zz14_RootAspMenu">
        <li class="static">
            <a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/">
                <span class="additional-background ms-navedit-flyoutArrow">
<span class="menu-item-text">Defra Benefits Dev</span></span>
            </a>
            <ul class="static">
                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Project Information</span></span></a></li>
                <li class="static selected"><a class="static selected menu-item ms-core-listMenu-item ms-displayInline ms-core-listMenu-selected ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits</span><span class="ms-hidden">Currently selected</span></span></a></li>
                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits HIDDEN</span></span></a></li>
                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits HIDDEN</span></span></a></li>
            </ul>
        </li>
        <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="javascript:PDPInfrastructure.NavigateWSSPage(0,true)"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Project Site</span></span></a></li>
    </ul>
</div>

```

I have tried the following with no luck

```
<script>
$(document).ready(function() {
    $("#zz13_idPDPQuickLaunch *:contains('Benefits HIDDEN')").hide ();
});
</script> 

```
