1 . Create Master List with following Content Type Activity Area Category Document Economy Inquiry Document Economy Service etc. 2. ON your form (image : Content type) Add button upload file - and open your custom upload in model pop up (/customupload.aspx?CT=Document) pass your content type as Query param 3. Bind first drop down on load by querying to your master list and retrieve all ActivityArea 4.
