checkbox
A checkable input that has three possible values: true, false, or mixed.
Widget roles act as standalone user interface widgets or as part of larger, composite widgets.
Description
A checkable input that has three possible values: true, false, or mixed.
The aria-checked attribute of a checkbox indicates whether the input is checked (true), unchecked (false), or represents a group of elements that have a mixture of checked and unchecked values (mixed). Many checkboxes do not use the mixed value, and thus are effectively boolean checkboxes.
