 Accordion menus follow the basic [Menu](menu.html) syntax of `<ul>`, `<li>`, and `<a>`. To convert a basic menu into an accordion, add the attribute `data-accordion-menu`. You probably also want it to be vertical, so add the class `.vertical` as well.
 
-Use `<span>` for elements that should open a nested menu.  Use `<a>` for links outside of the behaviors of the menu functionality.
+Any `<a>` will behave like a standard link. However, any `<a>` paired with a nested `<ul>` menu will then slide that sub-menu up and down when clicked on.
