Consider cascading menu position
When you're designing cascading menus, it's essential to be mindful of the available screen real estate. Utilize wireframes or mockups to anticipate how the menus will unfold, ensuring there's enough room for each option to be clearly displayed.
You can use design tools that allow for dynamic adjustments, so you can simulate different scenarios. This way, you can adjust the direction or structure of the menus based on the actual space constraints you encounter.
