TriggerComboBox / ComboBox expanded style

[shaun]

It would be great if the Coolite.Ext.TriggerComboBox (or Ext.form.ComboBox) were extended to apply an additional style to the combobox_container while the combobox's dropdown (x-combo-list) is visible ... perhaps something like 'x-combo-open'?

This additional style on the combobox_container (not the x-combo-list) would allow for better styling of custom comboboxes.

See the attached ComboBox extender which adds the new style class I am asking for (and also implements the interfaces described at http://forums.ext.net/showthread.php?4267).

It would be great if this functionality could become part of coolite, so I don't have to use an extension class.
