Using with "MultiExtended" Selection mode with ComboBoxExt

Hi, I''m looking at the sample in "Extension Suite Sample Browser" ''Tools'' section named ComboBoxExtDemo. The control is great! I wish to have a listbox ''with checkboxes'' bound to the combo box and allow users to use the MultiExtended mode. Unfortunately, whenever they click on an item in the listbox the control collapses. Can you please tell me how I can keep the combobox expanded whilst they make multiple selections? The box should only close when they click the down arrow. Thanks very much in advance, Damien
