Interface ToastOptions

When false, the toast renders without its close (×) button so the user can't dismiss it. Use for persistent in-progress toasts whose underlying operation keeps running regardless of the toast — a dismissable × there reads as "cancel", which it isn't. Defaults to dismissable.

When true, the message is rendered in a monospace font — e.g. a raw error string.

Notes to render as reference links in the toast body — e.g. the notes an action affected or that triggered the message. Each is shown with its icon and title and navigates to the note on click. A plain string is shorthand for a ToastNoteReference without annotation.

Optional heading rendered above the notes reference-link list.

Invoked once when the toast is removed, whether it auto-hid after its timeout or was dismissed by the user. Useful for resetting state that accumulated while the toast was live (see notes).

When true, the toast renders with a wider maximum width than the default. Use for toasts with richer content — e.g. a notes reference-link list — that reads poorly cramped.
