Dropdown/expandable menus reveal additional options when a navigation item is clicked or hovered over.

Heatmaps capture a snapshot of the page upon initial load and then track all clicks, mouse movements, and page scrolling. If a dropdown/expandable menu is opened by a click (as opposed to a mouseover), heatmaps will display those clicks. However, since the heatmap snapshot is taken during the initial page load before any menus are expanded, it does not display the expanded menu content itself, nor any clicks within those expanded sections.

Note: The behaviour described here is a general guideline. Depending on your specific implementation of menus, your experience with how heatmaps track these elements may vary.
