createChildSymbol inside content box

Hi all,

rather stuck...

So i have main stage - with a content box on it

Buttons can be clicked and they call up a symbol inside the content box using this code:

sym.$("content").empty();

sym.createChildSymbol("blah", "content");

works great - but I've got so many buttons now I needed to create a nested drop down menu - which looks great...

but now none of the menu buttons work with the code I have above - either nothing happens or bits of the menu disappear or other strange happenings!

I've put

sym.getStage().$("content").empty();

sym.getStage().createChildSymbol("blah","content");

But that doesn't work, I also tried getComposition too but that doesn't work either.

Does anyone have any suggestions?

Thank you
