I have a question about how Ajax-powered dropdowns could work...
If I have a drop-down list of companies, a drop-down list of states/provinces, and a drop-down list of cities, and I want to be able to filter records in a database based on those dropdowns, could I let a user choose any item from any of the three dropdowns (ex. they could choose a city, a company, or a state/province) and use ajax to repopulate the other remaining two dropdown lists?
So if they chose a city, then the state/province dropdown would repopulate to the respective state/province where that city is, and the company dropdown would repopulate to only companies that are in that city?
Is that possible? Or is it necessary to define a hierarchy or order to the series of filters?
Does anyone have an example of something like this?
There are a series of 3 different drop down menus: MAKE, MODEL, COLOR. In this series, selecting a MAKE populates the MODEL dropdown, which in turn populates the COLOR drop down. You MUST choose a MAKE first... What I want to do is make 3 dropdowns where it doesn't matter what order you select them in..
So if we choose 'champagne-silver' under COLOR, the other two drop down menus would repopulate so they would show all of the MAKEs that have vehicles in that color, and the MODEL menu would be repopulated with all of the MODELs (from all the MAKES) that are available in that color..
