To
add a content type to a list or library, you first enable management of
content types in that list or library. To do so, go to the list or
document library settings page by switching to the List ribbon or
Library ribbon and clicking the List Settings or Library Settings
button.
At the top of the page, in
the General Settings section, click the Advanced Settings link. On the
Advanced Settings page, shown in Figure 1, select Yes under Allow Management of Content Types? Then click OK at the bottom of the page.
You then return to the list or library settings page, which now has a section for content types (see Figure 1).
To add a content type,
click the Add from Existing Site Content Types link in the Content
Types section. The content type selection page appears, enabling you to
select one or more content types to add to the list (see Figure 2).
On this page, the available
content types appear in the box on the left. Select the one you want
and click the Add button to move it to the box on the right (which
shows the types you selected). If you want to remove a content type you
added by mistake, select it from the box on the right and click the
Remove button.
When you are finished
selecting all the content types you want for the list or document
library, click OK. The resulting list or library settings page shows
the list of content types available in the list or library.
