Keep drop down list open while typing in the field
Description of the issue
Is there any way to keep a drop down list to stay up while I am typing in the field. I have a drop down list of cities that is very expansive. I want to be able to start typing Por and have it stay open while I see the options go from all options, to all options that start with P to all options that start with Po to all options that start with Por until I only see the value that I need.
