There is no easiest method then to use Auto Complete Widget. The auto-complete field provides suggestions while you type into the field. This will ease the process of filling out a form. If you have a dropdown list of more than 100 entries, the dropdown becomes unusuable for the users. So, it is recommended to use an autocomplete field in such case.
