same question here….
I added a country selectbox to the search-form.php:
<select id="widget_location_country" name="location_country">
<option value="Deutschland" selected="selected">Deutschland</option>
<option value="Deutschland" >?sterreich</option>
<option value="Schweiz" >Schweiz</option>
</select>
I I thought geo-mashup-search.php could add that country to the search_text at the load_template function, but that does not work.
