aria-required

Boolean

Indicates that the user must provide a value for a field before the form can be submitted. Screen readers announce the field as 'required' so the expectation is clear up front. On native controls prefer the `required` attribute, which also triggers browser validation; use aria-required for custom widgets.

aria-required="…"

Values

true: User input is required before submission.
false (default): User input is optional.
