Site Structure & Navigation

How to find stuff.

• The menus at the top represent the main sections of the website.

• Each section has its own expanding tree-type table of contents in the left hand side-bar.

• The homepage shows the top table of contents, including the main sections, in the left hand side-bar for a quick overview.

• The table of contents of the current page is shown on the right hand side.

• Both tables of contents (structure left, page right) only show if the window width allows so.

• The left hand side menus tree maintains its sub-items open/closed status when navigating between main menu items. You can close an item by clicking on the chevron marking a sub-tree.

• On a small screen, the main menu presents as "hamburger" icon. It opens the main items as pop-over. After selecting a main menu section, use the list of contents items on the sub-section page to drill down, and the browser back-button and the breadcrumb links at the top of each page to navigate further.
