Attribute definitions

disabled [CI] When set for a form control,this boolean attribute
disables the control for user input. When set,the disabled attribute
has the following effects on an element:

Disabled controls do not receive focus.

Disabled controls are skipped in tabbing navigation.

Disabled controls cannot be successful.

The following elements support the disabled attribute: BUTTON,INPUT,
OPTGROUP,OPTION,SELECT,and TEXTAREA.

This attribute is inherited but local declarations override the
inherited value.

How disabled elements are rendered depends on the user agent. For
example,some user agents “gray out” disabled menu items,button
labels,etc.

In this example,the INPUT element is disabled. Therefore,it cannot
receive user input nor will its value be submitted with the form.

06000

Note. The only way to modify dynamically the value of the disabled attribute is through a script.
