Just want to ask how can I cross-site list lookup using sharepoint 2010.
I’ve created two Sites. TestSite1 that has a list called
List1 and TestSite2 that has a list called List2. The problem is when I tried to create a lookup column in List2 so I could see the List column in TestSite1 I could not find it.
How can I do this using the OOTB SharePoint 2010?
Thank you in advance.
