Action menus slide up from the bottom of the screen when users press a button or attempt to take action. They have an excellent location within thumb-reach and are meant to present the most common, high-value tasks.

Additionally, there are context menus that appear after long-pressing the element, blurring out the background. The main drawback of context menus is that there's no visual indication of their existence until they're activated.

Mobile developers often experiment with the menus' appearance, placement, and behavior. However, using native action menus is more beneficial for users as they experience less cognitive load and don't need to learn new patterns.
