combo items

I use file to set the items option in a combo.

I want to ask I can select the optional items showing in a combo box.

e.g. I set 5 options in then I only want to show 3 options in a case.

I want to ask this case can work or not ?

Thanks for your help !

You mean TO HIDE or TO SHOW IN ONE TIME?
If you mean to show 3 of 5 in he list height - use method setOptionHeight(height)

If you mean hide - there is no ready approach.
