4.8.2 How to use check box parts (guide area)
You can use check box parts effectively, for example, in the following cases:
-
Options are fixed (when multiple options can be selected together).
-
The content of input is fixed, or you want to save the user the trouble of input.
-
An operation or checking is required.
If you specify the setting to display an error message when a check box is not selected, a user's error in operation or checking can be prevented.
