Fieldset

A <fieldset> groups several related form-fields (and their <label>s) together within a single <form>. A <legend> inside of a <fieldset> provides a caption that describes the field grouping.

A <fieldset> groups several related form-fields (and their <label>s) together within a single <form>. A <legend> inside of a <fieldset> provides a caption that describes the field grouping.

The default browser-defined styling for a <fieldset> and <legend> doesn't fit with our desired style, so SWAN features its own Fieldset component that overrides the default. This lets you make use of the nice accessibility benefits of <fieldset> and <legend> without having to use the browser's default visuals.

Accessibility

  • All <fieldset> tags must have a <legend> tag that labels them, for accessibility. If the information in the legend is superfluous to sighted users, the legend can be hidden on screens by making it.
  • The <legend> cannot be (or contain) a heading (H1-H6) tag. If the page structure requires a heading to label the form fields, don't use a <fieldset> tag. Instead, group them using a wrapper tag that has the role="radiogroup" attribute (for radio buttons) or role="group" attribute (for everything else), plus an aria-labelledby attribute whose value is the id of the heading.

Implementation

  • Note: the React component is spelled FieldSet with a capital "S", as if "field set" were two words, whereas the HTML tag is <fieldset>. This was an oversight; sorry.
  • Fieldsets are for sets of form elements. If there is a single form element, don't use a fieldset.
