I see the method of getting second class name with jquery but how do I do it in mootools , my element is `<li class="parent active">` 

I need to match full class name like li.parent.active and adjust height if that class is present I tried
 `$$('li').hasClass('parent active')` or getProperty but all of them return true even if active is not present, if I add **.parent.active** I get 

*The expression is not a legal expression*. now I **must** support mootols 1.1 ,1.2 ,1.3 working on CMS here so I started with the ugly one 1.1 version

this is how is actually needed

```
var holderdiv =$('mymenu');
if($$('li.parent.active')){holderdiv.setStyle({'height':'50px'});

```
