Edit not working for DropdownList

[cb-aravindh]

@jquense Initially I start typing and select the value from the dropdown list, If I want to change the value I need to start typing from the beginning, Here while changing the value I want to start typing from the end of the current value.

Eg: I have three values in the dropdown list

1. 123
2. 12345
3. 1234567

First I selected option 1 ("123") If I want to move to the second option("12345") for this I need to start typing 12345 from the beginning instead of just adding 45 at the end. Any idea how to handle this?
