That was it - thanks! BTW just FYI it seems that this will only collapse the first collapsible object. In my case this works out well.
BTW, I've noticed that the 'configs' I see exposed via aware.js thru the advanced/initialization script feature include:
Form Title: config.title = null;
Form/Query Bar: config.preventHeader = true;
Form/Query Bar Collapsed: config.collapsible = false;
Form/Query Icons: config.iconCls = null; or config.iconCls = "{css class};
Form/Query Tool Icons: consconfig.tools = null;
Thanks again hpl123!
