Filter between radio button and comboBox


I am currently developing an application for requesting directions and would like to make sure that when I decide to choose "Local" as a destination, I manage to select in the "destination city" field some local cities. While, when I choose Abroad ", the foreign cities are displayed in the" destination city "field so that I can choose a foreign city.

I would therefore like in a simple way to bring out the cities according to the destination. when I click on "Abroad", the local cities must not appear in the "Destination city" field and vice versa with the possibility of entering another city which is not in the list.

Thanks for the help !

Looking forward to hearing from you in the comments.
