How can a search result look like this?

how does a site get multiple listings in G SERPS?

[uhwebs]

I searched for widgets and came across a Google result that looked like:

Widget Website
description of website...
www.widgeturl.com/
red widgets - widgeturl.com/redwidgets
blue widgets - widgeturl.com/bluewidgets
widget care - widgeturl.com/widgetcare

Google listed multiple pages of theirs under a search. All other results were just Title, Desc, URL like normal.
How did this site get to be listed like this?

Google has started calling it Site Links, and in the past it's been called "Extended Listings" by webmasters. Here are some past threads in the Google Search Forum:

Google adds information on SiteLinks (extended listings) [webmasterworld.com]
Google SERPS - subcategories with site links in the description [webmasterworld.com]
Extended description at #1 -- now PLUS a #2 result [webmasterworld.com]
Does Google Sitemap help to get "extended listings" [webmasterworld.com]
