You can't add to default search bar, but you can create GMW form and place
it in header. Theme option - header option - header layout, choose header
;ayout with code zone. Then, you can add shortcode of form in theme option
- ads option - in first text area

Igor,

I asked Geo my WP about this, but they have not answered in more than 2 weeks. So I have to ask you:

Can  I add LOCATIONS to my search bar?

I want the search bar to have one drop down menu with a list of countries.

But the first one must be 'All Countries' because some Jobs might not be just 1 country, it might be a remote freelance job people can do anywhere in the world.

So the drop down menu on the search bar must say 'All Countries,Afghanistan, Albania, Algeria, Andorra, Angola,... etc 

Can I create this feature maybe with a premium extension from Geo my WP?

Sorry for the trouble!

Thank you!

Sim
