Dependant Fields for Classipress?
I'm building a classsified ads website using classipress but I want it to be as user friendly as possible. I would like to create dependant fields for some categories when a user is posting an ad or when he/she uses the refine search when on the ad category page. An example of what I want can be seen initially when posting an ad - selecting the category>then the sub category dependant on the category selected.
TO further clarify, for instance, if a user selects Automotive>Cars. I want the next form to have a drop down "Make" then dependant on make selected the "Models" would show up for selection in another drop down box and so forth. I don't have any tuition with php but I cant grasp well. Any guidance would be appreciated
