Exploring Custom List Templates
Custom list templates are very similar to custom site templates except that they are narrower in scope. With list templates, you can create your own custom list types to complement the existing list types such as document libraries, announcements, and links.
As we did in our explanation of custom site templates, we will create a customized list. In the following scenario we customize a document library.
Saving a Custom List Template
The list template is saved through the SharePoint web user interface, which empowers users and avoids the need for administrative intervention. Now that we have a customized list, we are ready to save it as a custom list template for others to reuse. The following steps demonstrate how to save the custom list template.
Select Save Document Library As Template, as shown in Figure 1.11.
Fill out the Save As Template page (see Figure 1.12) as appropriate and then click OK. You can always change the filename, template title, and template description later in the template library. At this time you must decide whether to include the list content.

After completing the previous steps, the template is now saved. SharePoint confirms that the operation completed successfully as shown in Figure 1.13, which immediately displays after clicking OK in the Save As Template page.

You manage the List Template Gallery through the Top-level Site Administration (refer to Figure 1.6) page just as you manage the other site collection galleries. Because the List Template Gallery exists at the top-level site, the newly created custom template is only accessible from that site collection. This important caveat enables you to isolate custom list templates from other site collections. If you want to make a list template accessible within another site collection, you simply need to upload the desired custom list template to the desired site collection’s list template gallery.
The List Template Gallery (see Figure 1.14) is also a customized document library for an entire site collection, which explains why our newly saved template (file) can only be used in the current site collection and not other site collections. It also implies that the template is wholly contained within a single file.

Through the List Template Gallery, the custom list template filename, title, and description are all editable. Thus, if you are unhappy with the values you specified for them in Figure 1.12, you can change them.
Applying the Custom List Template
The next time you create a list or library, your new list template will appear on the CREATE.ASPX page. In our example, Customized Document Library appears as a choice (see Figure 1.15). In fact, all custom list templates for the current site collection will also appear on that page. Notice that the title and the description that we specified while saving the custom template are reflected on the CREATE.ASPX web page.
