Hi Phuong,

Can you please share the custom handler you have? It will be event best if you can replicate the problem in a Doj demo so I can fully understand the case. You can use the following one as a starting point:

thank you for your support. the solution is i save the event handler of arrow keys (keydown event) and prevent this when popup is closed (user has not input) and push this event when popup is opened. I use .data("events") of Jquery. 

P/S: I think MultiColumnComboBox should have options for posible to select item when user has not input anything in this.
