Expose filter by city with admin selected cities

Hello everyone,

I have location and I have a content type which define several market places in different cities.

I'd like to create a filter by city which show a dropdown menu with only the biggest cities of the country which of course I can configure myself, because for now the filter I can apply is not a dropdown list but a textbox where the user enters the city name.

Is it possible to have a dropdown list with cities defined by myself as filters ?

Thanks,
