Checkbox

Rich label content, such as text with a link. Overrides Label.

Shows the box as partly selected (a dash), such as a "select all" box when only some items are. Display only: it posts as unchecked, and choosing the box clears it. With script, screen readers announce it as "mixed". A Switch doesn't take it.

Which side of the label the box or switch sits on. End puts it at the end of the row, with the hint and errors under the label, as in a list of settings. Defaults to Start.

An icon before the label, such as a key for a security setting. With ControlPosition.End it's centered on the label and hint, at the start of the row. Decorative: screen readers read only the label. Use icons on every row of a group or none.

The value, bound with @bind-Value.

The field's name in validation messages from the input itself, such as a value that can't be parsed.
