Navigation menus in School Loop version 2 are designed for clarity without clutter. This article explains the sections of the navigation bar.
School Loop Version 2
The main navigation bar includes the level 1 sections. The drop-down menu for a level 1 section goes down to level 2 sections.
The Interior page navigation includes breadcrumb links showing the path to the current page and side navigation links that go down to the next lower level.
When a user navigates down into a level 2 section, the breadcrumb navigation displays the entire path. The side navigation menu displays only the pages at that level and stops at the next level down.
Even at the deepest level section in this example, the breadcrumb navigation allows the user to navigate up to any higher level section while the side navigation menu remains uncluttered.
