Alternative forms allow you to create additional versions of editing forms for page types, which you can then use in different situations. See Creating alternative forms for more information.
In Code names of automatically used alternative forms, you can learn about special code names of alternative forms. If you create an alternative form with one of these names, the system uses the form automatically for a specific purpose.
The following example demonstrates how to create an alternative form for a News page type (the page type and its fields are only an example, you can apply the same principles when working with your site's page types). The alternative form customizes the editing interface displayed when creating news articles in the Pages application.
See Extending the page type listing filter for another practical example of using alternative forms with page types.
Create an alternative form for the News page type:
The system creates a new alternative form.
After you create an alternative form, you can change its fields using the field editor.
The alternative form is ready to be used. If you open the Pages application and create a new News page, you can see the modifications made in the alternative form:
If you edit an existing News page on the Content tab, the original default editing form is used.
