you will have some issues if you apply this technique to ui widgets that overlay and are appended to the body - dialog, datepicker, autocomplete....

in the case of autocomplete, you can do the following to get a parent element with the scoped class - adding the scopped class to the UL of the autocomplete itself is not enough.

jQuery('.autocomplete').autocomplete({
    source: function(request, response){
        {....}
    },
    create: function(event, ui) {
        jQuery('.ui-autocomplete').wrap('');
    }
});
