dropdownlist: prevent opening in onOpen event

[Maksim]

1) http://jsfiddle.net/3ML7s/3/
now uncomment data  {text: "Item", value:"2"},
when I select vocabulary item I open a popup window
which inserts new value into dropdown and closes it, for simplicity, 'showModalDialog' replaced here by 'alert'

2) now comment data  {text: "Item", value:"2"},
when there no real items (just 'empty' and 'vocabulary') I need to open vocabulary immideatly
when popup closes dropdown widget stays still open
but I need mimic 1):
close dropdown and switch to empty item

How can I do this?

Hello Maksim,

You can prevent the opening of the DropDown's popup by calling e.preventDefault() on open event.
Please check the updated jsFiddle example: http://jsfiddle.net/3ML7s/6/
