Navigation focuses on solving the users' problems of where to go and how to get there. Generally it can be categorized into 'sidebar navigation' and 'top navigation'.
Choose the right navigation
An appropriate navigation gives users a smooth experience, while an inappropriate one leads to confusion. Here are the differences between sidebar navigation and top navigation
Fix the navigation at the left edge, thus improves its visibility, making it easier to switch between pages. In this case, the top area of the page holds commonly used tools, e.g. search bar, help button, notice button, etc. Suitable for background management or utility websites.
Level 1 categories
Suitable for simply structured sites with only one level of pages. No breadcrumb is needed.
Level 2 categories
Sidebar displays up to two levels of navigation. Breadcrumbs are recommended in combination of second level navigation, making it easier for the users to locate and navigate.
Level 3 categories
Suitable for complicated utility websites. The left sidebar holds first level navigation, and the middle column displays second level navigation or other utility options.
Conforms to the normal browsing order from top to bottom, which makes things more natural. The navigation amount and text length are limited to the width of the top.
Suitable for sites with few navigation and large chunks.
