Consider the use of drill down navigation
WCAG 1.0 Priority 2
WCAG Guideline 13. Provide clear navigation mechanisms.
Display of navigation hierarchy trees takes up valuable screen space on mobile devices which is a limitation that is not so severe on web-based browsers.
Requirement
Only navigation options that are related to the page being viewed are displayed on the page.
Recommendation
Multiple, hierarchical navigation displayed together on a page gives users too many choices and may be confusing.
Displaying limited navigation to conserve screen space creates its own navigation problems, which can be overcome by providing escape points. These should be incorporated into the page. Examples of these would be links to the next section, to the parent section, or to the home page. These links usually work best at the bottom of the page and allow the user to move on without scrolling back to the top of the screen.
Checking Tool
View the page in a mobile device.
