Q: I’m having trouble understanding the role of the Start Level/End Level function in developing a menu, as described in the “Styling Menus Vertically” video. What is the key to understanding this function?
- A: The Start Level and End Level are the way a menu is segmented, to show all or part of that menu.
By default, the Start Level and End Level are set to 0. This means that the entire menu will show.
If you would like to have just the top level navigation show (perhaps for a top menu bar), but none of the secondary, tertiary, or deeper navigation, set Start Level to 0 and End Level to 1.
If you would like to have just the secondary navigation show (i.e. you're in the "about" portion of the site and you'd like to have the about secondary navigation show on the left side of the page), set the Start Level to 1 and the End Level to 2. If you'd like to show all of the navigation (secondary, tertiary, and any deeper navigation), set the Start Level to 1 and the End Level to 0 (i.e. infinite).
The only tricky part about setting the Start and End Levels is that zero means different things in different locations.
For the Start Level, zero means the very beginning of the navigation. Engineers start counting with zero, while we are normally taught to start counting with 1, so this may be the cause of some confusion. This means that 1 actually corresponds to the second level, 2 to the third level, and so forth.
For the End Level, zero indicates "infinity", or however far out the navigation goes.
