If you mean when you click the "Add new request" button and there's content that displays on the following screen, that's done with a template and the tag. That tag is what creates a text box along with a button.

The template that contains the preloaded text for adoption requests can be seen at Template:Forumheader/Adoption requests. On your wiki, you can give the template any name you want.

Here is the code being used on the page for adoption requests:

prefix=Adoption: width=60 default=Enter wiki name here - example: Fallout Wiki‎‎ preload=Template:Forumheader/Adoption_requests buttonlabel=Add new request

Note that the  parameter is the part that automatically loads the content of the template when the button is clicked.

Let me know if that's not what you were asking.
