Layouts
Six arrangements of the same shell. The choice is remembered, and every page in the demo uses it, so pick one and keep reading.
Application
The default. Grouped navigation with icons, and plus-minus disclosure.
Sectioned
Several titled sections, sentence case, chevron disclosure.
Documentation
A version switcher and a sidebar search, over a flat list with no icons.
Documentation, collapsible
The same, with each section able to fold away.
Documentation, marked
Sections open, and the current page marked with a rule rather than a fill.
Icon rail
Icons only, for a dense application where the labels are learned.
