ARIA: aria-readonly attribute

The aria-readonly attribute indicates that the element is not editable, but is otherwise operable.

Description

When you want to indicate that an interactive element works but is not editable, set aria-readonly="true". This indicates to the user that an interactive element that would normally be focusable and copyable has been placed in a read-only (not disabled) state.

When aria-readonly is set to true, it means the user can read but not set the value of the widget. Read-only elements are still relevant to the user, so you should not prevent the user from navigating to the element or its focusable descendants or copying the value.

Examples include:

• Form elements which should not be changed.
• Row and column headers in a spreadsheet.
• The total value in a shopping cart.

If the non-changeable value shouldn’t be able to receive focus, use aria-disabled instead.

[!NOTE] When using semantic HTML form controls, if you set the readonly attribute, you don’t need to include aria-readonly="true".

[!NOTE] The value of <input type="checkbox"> can not be edited making readonly not relevant. However, when creating checkboxes with role="checkbox" the aria-readonly attribute is supported.
