The fact is that, initially, checkboxes are not supported for the map form because they take too much space on the form and are not so effective for filtering listings on the map
But you can enable them editing some files:
1. In admin/controllers/search_forms.inc.php > at the bottom find this code:
PHP Code:
Only registered members can view the code.
and replace it with:
PHP Code:
Only registered members can view the code.
2. Then go to templates/general_rainbow/tpl/blocks/fields_search_horizontal.tpl
at the bottom, before the last {/if} add:
Code:
Only registered members can view the code.
3. Finally, open templates/general_rainbow/controllers/search_map/search_map.js
find:
Code:
Only registered members can view the code.
and replace all occurrences with:
Code:
Only registered members can view the code.
