The HTML & lt; fieldset & gt; tag groups related elements in the form, and the fieldset form

The HTML <fieldset> label groups related elements in the form, and the fieldset form.

<Fieldset> the label packs a part of the Form Content and generates a set of related form fields.

When a group of form elements are placed in the <fieldset> label, the browser displays them in a special way. They may have special boundaries and 3D effects, or you can even create a subform to process these elements.

<Fieldset> the tag does not have a required or unique attribute.

<Legend> the label defines the title for the fieldset element.
