Using Umbraco v6.0.4

-With in Developer - dataTypes -created var called ParentProduct -Property Editor = Content Picker -Database Datatype = ntext

-With in Settings - Document types -Modify Page - Product -Add new property to Generic Properties tab -Name = Parent Product -Alias = parentProduct -type = ParentProduct

When I go into add content I fill in all my fields on the last tab ( Properties ) I have a field called Parent Productit allows me to select from the list of current content and puts the item I select into the text field

Then next thing I want to happen is on the main web page that show the content I want user to be able to se the product they chose from web and then a drop down list that show other products ( child product to the parent)

example if I have a white tee shirt as the parent product and i mark 3 other pieces of content ( red blue green) as and refer them to the white as the parent. I want to be able to see in the list the red blue green and then when I select red I am taken to the red content page. My question is how do I do that ???
