I am working on a SharePoint Enterprise Server 2013, and I have created a custom list. Then I try modifying the default content type for the custom list, so I try adding the built-in Document content type inside it. But it seems the Document content type is not available inside the content type list, as follows:
So can anyone advise on this please? Now I am following this approach, because the Custom list offers "Item-level" permission unlike the built-in Document library. So I was planning to create a custom list (which provides an "Item-Level permission" section), then to add the built-in Document content type inside it, so I will end up having a Document library which have an Item-Level permission section, but it seems this is not available.
