Using a caret or arrow icon to indicate submenus is an essential navigation practice. This small but effective visual cue clearly signals to users that more options are available under a specific menu item. For example, in an educational app, a downward-facing arrow next to the item “Courses” signals that users can explore further into detailed categories or specific course offerings within that section.

This helps prevent confusion and improves user interaction by making the structure of the app more intuitive. Users can easily see which items lead to further content and which are direct links, enhancing their overall navigation experience.
