Examples of column-based navigation in a phone and a desktop UI.
When to Use¶
Column-based navigation is ideal for navigating through a hierarchically organized information space, where users often go back and forth between different levels of the hierarchy. For example:
Accounts ->Folders -> (Sub-Folders) -> Mails -> Individual mail
Folders -> RSS Feeds -> Feed items -> Individual item
File system hierarchy
Kirigami implements this pattern in the form of a PageRow, which allows users to scroll horizontally through pages and allows the application to add and remove pages to and from the stack dynamically. This allows easy back and forward navigation through the hierarchy by swiping left-right on touch screens.
A header with the title of the current page doubles as a breadcrumb trail which the user can scroll through and tap to go to a specific page.
How to Use It¶
Use one page/column for each level of the hierarchy (or more generally, for each step of the navigation).
Make sure to set meaningful but short page titles, so they can create a useful breadcrumb trail.
When on the lowest level, showing the content of an individual list item, use a swipe beyond the top/bottom of the content to jump to the previous/next item in the list.
