How to display all existing locations in external career site

Hello all,

We would like to display all our locations by default in the Locations filter dropdown on our external career site :

By default it only lists 10 locations and it is not very convenient for candidates to filter as they may not know all our existing locations, so filtering via the search box is not very helpful.

How can we remove that limitation to 10 locations ?

Thanks for your help.
