Mutiselect Dropdown with a single item? (hide mobile keyboard)

Hello,

I use the “Multiselect Dropdown” plugin mainly for the possibility of searching in fields. I set the maximum item to “1”.
When I select an item, the input remains focused, with the message “Please select fewer items”.
The problem is that on mobile the keyboard remains open.

Do you have any idea how to remove the focus after selecting an item?

I looked on the workflow side, but found nothing functional.

thank you!
