The busy state informs the user about an ongoing operation in a specific control, such as a button or a table. It is displayed without text.
- Use the busy state if you want to show that there’s an ongoing operation for a specific control, such as saving a table, and you want to block the user from acting on that control.
- Use the busy state if the operation takes more than one second.
- Avoid showing multiple busy states at the same time on the same screen.
- Don’t use the busy state if the operation lasts less than one second.
