Adaptive Component - Curtain Panel Sub Categories

[amstaples]

Hi Team,

I've created an adaptive component to finish off the edges around a curtain system. What I would like to do is give an element in my adaptive component a 'Panel' sub category under the 'Curtain Panels' Category. For some reason, when I create the 'Panel' sub category under 'Curtain Panels', I'm not able to chose this from the properies box when I have the element selected. Any ideas as to why this could be?

Just to be clear I'm using 2011 for this project. In 2012 it is possible to do this.

Thanks in Advance
