Hi,

I am looking for a way to do something similar to what Country / State or Province dropdowns do on some sites. That is : 2 dropdown, 1 for country, 1 for province. When you select an item in Country, the Province dropdown fills out with only the provinces of that country.

My case is not quite as simple though (the data is not static and it is instead based on umbraco content). Instead of Country / Province, I am working with Categories and Items.

+Parent
    + Category1
         Item1
         Item2
         Item3
    + Category2
         Item4
         Item5
         Item6
    + Category3
         Item7
         Item8
         Item9

Then I have document type on the site that I want to link to the items. The document type has a few properties, including a Category and an Item :

Title
Description
Category (Dropdown list that offers "Category1", "Category2", "Category3")
Item (Dropdown that offers items based on the selected Category)

I was thinking that the way to do this would be to create 2 new data types, both of type Ultimate Picker.

• The first one only takes the nodes under Parent of the document type Category.
• The second one only takes the nodes under Parent (with Show Grandchildren activated) of the document type Item

I looked at a few solutions like Embedded Content but that only really groups properties together, it doesn't filter. I also need to be able to search based on the 2 properties using Examine so something like the SQL DropDown list where I manage my categories and items myself outside of Umbraco doesn't really work for me either.

How should I achieve this?

Thanks a lot for your help!
