User filterable list
I've got a user filterable list set up to filter jobs based on text found in the job title and a location <select>.
In the location <select> there are several locations - North West, South East, etc. There's also an All Areas option which when selected should just display all the jobs.
I can't figure out the best way of doing this? Obviously 'All areas' isn't a value in a field and as such isn't marked against any jobs.
Any help or pointers would be really helpful.
