        All arguments must be passed by name, with the exception of 'name',
        which may be used as a positional argument.

        If name is specified, then the item must have the indicated name.

        If label is specified, then the item must have a label whose
        whitespace-compressed, stripped, text substring-matches the indicated
        label string (eg. label="please choose" will match
        "  Do  please  choose an item ").

        If id is specified, then the item must have the indicated id.

        nr is an optional 0-based index of the items matching the query.

        If nr is the default None value and more than item is found, raises
        AmbiguityError (unless the HTMLForm instance's backwards_compat
        attribute is true).

        found, raises ItemNotFoundError.
