Why ArtfulBits Cross-Site Lookup?

Default SharePoint Lookup supports only lookup within the same site, so if you need to lookup data from another site, you cannot use it. ArtfulBits Cross-Site Lookup allows users to refer to a list from any site in site collection.

If list contains large amounts of data, it is not very efficient to search for some data using standard SharePoint lookup. ArtfulBits Cross-Site Lookup with Picker Dialog helps to resolve this issue. You can search/filter data in picker dialog, which helps to find the required item quicker.
