Menus: Presenting hierarchical or meta choices
Menus provide an economical
way of displaying a site's
main features. Where maps tend to show spatial or structural relationships,
menus are usually text or text with
graphics anchors arranged in a hierarchical
order. (Many sites have a "site map" but this usually turns
out to be a menu cataloguing most of the website's pages).
Writers use these simple text menus for various effects, which are intensified when these become the single anchor strategy:
The Hummer  site
won an award with a site using horizontal menus that covered half of the
image of the car. However, it reverted to a top-down menu system on the
Efferent sites tend to either offer menus that link to all the nodes (e.g., Nevada Division of Environmental Protection ) or to major sections that then offer submenus to all the nodes in that section (e.g. FirstGov , Earthtrends , Hummer , Saturn , USA TODAY , BBC , and Bankrate ). These efferent sites tend to provide the site map list only on key pages such as the home page. The Royal Institute for Deaf and Blind Children has a variation on this, offering submenus on the relevant subpages only.
Some aesthetic sites, such as Afterimage's  and The Ballad of Sand and Harry Soot's have menus that offer all possible nodes at all times as well. Others, such as Disappearing Rain , have elaborate submenu systems that reach all nodes.
However, many aesthetic sites use limited menus to present a portion of the work. Same Day Test  and Joe's Heartbeat in Budapest  offer only limited anchors that the reader can chose from to respond to the content. Six Sex Scenes  and Penetration  use menus that present a small range of thematically connected destinations.
Menus come in a wide range of visual effects. Efferent sites can range from as simple as Nevada Division of Environmental Protection's highlights to a complex work in itself such as Doonesbury's entertaining main anchor and moving sublinks around the anchor.
Aesthetic sites also play within an enormous range: while Him  is grey and austere to the point of eliminating content on the anchors, High Crimson  provides a rich visual menu montage as the first menu flowers and other screens appear on top of that menu. Each new screen has the same menu, but the visual look and feel of the menu distinguish the portions of the feast.
Others such as The Ballad
of Sand and Harry Soot or War Games--Catch
The LandMine!!  use menus as a secondary
strategy to provide meta and supplemental information. Menus do not have
to be linear, nor have words, as the sphere menu in ~water
~water ~water  ably demonstrates.
Menus can also be merely long lists of anchors, as Earthtrends demonstrates. Earthtrends also explains each anchor on the side, thus expanding the menu content.
