can 2 sharepoint sites share access to the same Web part in SharePoint 2013? We have a task list we would like to share access to across 2 different Sharepoint pages from different groups with in our company. I am wondering if that is possible to shaer the access to the second site/page similar to a data share webpart.
You can share the list hwoever you want, then you can create a content query webpart in 2 different sites that point to that list, and it will trim security automatically.
Content query webpart, is normally for list or libraries in the same site collection.
