--- order: 8 title: Navigation --- Broadly speaking, anything telling users where they are, where to go and how to get there can be called navigation. When using navigation or customizing navigational structures, please pay attention to following common pitfalls: - Provide visual and contextual cues as many as possible, to prevent users from getting lost - Maintain consistency between form and behavior, or reduce the number of items in navigation, to decrease user's learning cost - Minimize page transitions (i.e. reduce the number of page tranistions required by a task from several to just once or twice), to ensure that user travels only a short distance from any page to another --- ## Menu Navigation menu is an effective and user-friendly way for reprensenting site structure to users. A proper form of navigation should be utilized, once the information architecture of your site becomes clear and stable. ### Top Navigation

Top navigation menu put hyperlinks in a row and present information in a simple and straightforward way. It is suitable for landing pages and consumer facing web apps. The number of first level menu items should be between 2 and 7. Title for each menu item should contain less than 15 characters. ### Side Navigation

Vertical navigation is more flexible than horizontal one, menu items are easily extensible downward, and longer labels can be allowed. With help from a scrollbar, unlimited number of menu items can be supported. It is suitable for multi-level, operation intensive and dashboard-like web apps. - More layouts with navigation: [Layout](/components/layout/)。 --- ## Breadcrumb Breadcrumb tell users where they are now among page hierarchy, and parent-child relationships between pages.

> Notes: > 1. When hierarchy is deep, it is recommended to hide certain pages. Depth of pages shown should at best be lower than 3, and should not exceed 5. > 2. Avoid using breadcrumb as much as you can, especially when page contains other navigation components sufficiently telling where users are. --- ## Tabs Tabs categorize content, in order to present large amount of information in a limited space.
