Mobile location switcher

How can we enable all cities in the selected region to show? Currently its only set up to show 5 cities. However, the “search” is not intuitive. If you input the city, it doesn’t load. To get to an unlisted city, you need to input the city, then use the drop down selector. Users should be able to input the city, then search(enter) to view the selected city…

But for a workaround, I would like to list all cities within a selected region. Is this possible? Thank you.
