The HTMLFieldSetElement interface has special properties and methods (beyond the regular HTMLElement interface it also has available to it by inheritance) for manipulating the layout and presentation of field-set elements.

See also:



A Boolean reflecting the disabled HTML attribute, indicating whether the user can interact with the control.

read onlyelements:HTMLCollection

The elements belonging to this field set. The type of this property depends on the version of the spec that is implemented by the browser.

read onlyform:FormElement

An HTMLFormControlsCollection or HTMLCollection referencing the containing form element, if this element is in a form.

If the field set is not a descendant of a form element, then the attribute can be the ID of any form element in the same document it is related to, or the null value if none matches.


A DOMString reflecting the name HTML attribute, containing the name of the field set, used for submitting the form.

read onlytype:String

The DOMString "fieldset".

read onlyvalidationMessage:String

A DOMString representing a localized message that describes the validation constraints that the element does not satisfy (if any). This is the empty string if the element is not a candidate for constraint validation (willValidate is false), or it satisfies its constraints.

read onlyvalidity:ValidityState

A ValidityState representing the validity states that this element is in.

read onlywillValidate:Bool

A Boolean false, because fieldset objects are never candidates for constraint validation.



Always returns true because fieldset objects are never candidates for constraint validation.



Sets a custom validity message for the field set. If this message is not the empty string, then the field set is suffering from a custom validity error, and does not validate.
