Remove country field from search module

I want to remove the country field from search module as I have only properties from one country.
Moreover I want the states from this country to be automatically loaded to the dropdown field.

Thanks in advance

Hi Dimitrios,
If you OS Property uses one country. The dropdown select list Country won't be shown at front-end. To select default country, please go to Configuration > Tab General > Select Default country at corresponding dropdown select list.
Thanks
