I've asked this question on the post-installation section but not come up with too much and then I stumbled upon this group when searching for a solution. I hope you don't mind me asking this here. it's for drupal 7.

I want to create a menu structure something like this:

Information about item location

Country
Area
City

I want to have 3 drop down boxes. When you select the country it will save that item in the "country" vocabulary. Then it will use the country that the user has selected to populate the area drop down box. When the user selects and item from this drop down box it will save that item in the "area" vocabulary and then it will use the area that the user has selected to populate the city drop down box with the cities that are in that area and then save that information once selected.

I've tried using the hierarchical select module but it just saves them all in the same vocabulary and I want to be able to have them as different ones so that I can filter by country, area etc. and not run the risk of having an area in some country called "London" and a city in a different country called "London" as well which might happen if I just kept them all in the same vocabulary.

I've tried to set it up with different vocabulary so that I have differnent categories, in this case I'd have a Country, Area and City category but then I can't populate the select boxes depending on the previous selection.

Any thoughts on how to do this?

Thanks
