To disable an element, you simply add the disabled attribute to it. This can be done on various form control elements, including input, button, select, textarea, optgroup, and option.

The disabled attribute affects various form controls differently, but input elements, such as text inputs, radio buttons, and checkboxes, become unusable and unclickable when disabled.

If you include a disabled fieldset in a form, no contents will be submitted with the rest of the form. This is because the disabled attribute causes all the form control descendants to be disabled.

Here's a quick rundown of the effect of the disabled attribute on a fieldset:
