Thank you for writing.
By default if you click in the dropdown (single click) the row is selected and the dropdown is closed. Also when you click in the text box the drop down is closed without any value change. This is the default behavior and I am not sure what is the expected one in this case. Could you please specify how exactly you want the control to behave? This will allow me to further investigate this case and provide you with a proper solution if such exists.
I am looking forward to your reply.
