HTML input readonly Attribute

The readonly attribute is used to make an input field non-editable while still allowing users to view and select its value. The field value is also submitted with the form.

• Prevents users from modifying the input value.
• The input field can still be focused and its value can be selected.
• Unlike disabled fields, readonly inputs are included in form submission.

Syntax:

<input readonly>
