    v4 v5  
    1 Not sure if this is intended but there are various examples of implementing a header (non selectable list element) but I've found that whatever I try and can't stop the default "ui-menu-item" class being applied to my listitem. I've managed to workout that the examples that work are using 1.8 but I'm using 11.0 and it's defaulting to the "ui-menu-item" and doesn't seem to be over-ridable.

    14         var self = this;
    15         $.each( items, function( index, item ) {
    16           self._renderItemData(ul, item);
    17           // prepended element still ends up with "ui-menu-item" class??
    18           if (index == 0) ul.prepend('<li class="ui-header"><span>Returned ' + items.length + ' record(s)</span></li>');
    19         });
    20         // attempt to hack css!
    21         ul.find("li:first-child").removeClass("ui-menu-item");
    22       };

    25 I've now pin pointed what I think is the cause it appears after 1.10.4 and is present in 1.11.0 it's in the refresh() method in menu.js (previously jquery.ui.menu.js).

    27 It looks like it's due to the requirement for an anchor to be present being removed (see https://github.com/jquery/jquery-ui/blob/3a61627a501cb7ba1ce80046bfabbff0f7f2f517/ui/jquery.ui.menu.js#L325 and https://github.com/jquery/jquery-ui/commit/3a61627a501cb7ba1ce80046bfabbff0f7f2f517#commitcomment-7591515)
