We can show the combobox dropdown by using open() method and can close the dropdown by using close() method.

I want to know the status of the combobox, whether it is presently showing the dropdown or not.

I can listen for onSelect event to detect its dropdown closer, but if the user presses escape key or ENTER without selecting any item, it doesn't invoke onSelect event too. But, onOpen event invoked while showing and closing the dropdown list. But, I can't find when it was actually invoked.
ie., while open() or close() method.

Any help will be appreciated.

Thank you.

Note:
Am using zk-bin-3.6.3 version
