I have 2 content types. Destinations content type and regions content type. In regions content type i give reference to destinations node reference.
I am building another content type called product where i give node reference to Destinations and along with it i give node reference to regions content type.
My problem is that i need to filter out the regions(node reference to regions) drop down based on what destination is selected from previous destinations drop down.
So how do i do this ? please give me some idea for this. Hope my question is clear.
