Make the email clickable

Take a look at this filter, it allows you to modify the listing template.

Copy the full code, and place it in the functions.php in your theme folder.

You see a my_textinput near the bottom, replace it on line 27 with email. This will access the val of the email key in the json response.

Change the <%= my_textinput %> on line 28 to this, and it should work ( untested though ).

<a href="mailto:<%= email %>"><%= email %></a>

You can replace email with phone, fax, url or whatever other data field you like to access.
