Is there any way to link parent site and sub sites?

Problem: I have one list on Parent site and I have a few other lists on sub sites. I am trying to create lookup columns in the parent site list to obtain the data from the sub-site lists. Is this possible? Please advise. Is this an out of the box feature on Sharepoint? Or do I need to get SharePoint designer and infopath involved?

Thank you in advance!

  • This isn't possible with Out of the box SharePoint features, you need to customize it.. – Arsalan Adam Khatri Aug 7 '14 at 16:25
  • Could you please provide additional info? Customize it how? – Ish Aug 7 '14 at 16:28
  • You could do something in infopath; use list lookups on the sub sites and filter on the parent somehow. I would probably write an html/js view using the JSOM/REST API and maybe knockout or angular to manage the html binding but if you're not developmentally-inclined you can hammer something together with infopath/designer as you mentioned – John-M Aug 7 '14 at 16:56

If you can reverse your requirement where the lookups are at a higher site than the list consuming them, then you can use site columns to accomplish this. Site columns only exist on the current site and it's subsites.

  • Thanks! But I still remained confused. I have 5 sites: A, B, C, D and E. The first four contain lists that I need to use in the last one. What you are saying is if A, B, C and D are at a higher site then the list in E then the lookup is possible? – Ish Aug 7 '14 at 18:05
  • See if this article helps clarify things: nothingbutsharepoint.com/sites/eusp/Pages/… – Steve Lineberry Aug 7 '14 at 18:06
