Fieldset
Ready

Fieldset is used to group together several related form components and a label. The usage of this component helps to make these groups accessible for assistive technologies.

Fieldset consists of a mandatory label, and optionally a caption, tooltip, and error. It can be used to group together buttons, form fields, checkboxes, and similar components.

Examples #
Open in new window 
<duet-fieldset label="Choose an option">
  <duet-checkbox checked label="Option 1"></duet-checkbox>
  <duet-checkbox label="Option 2"></duet-checkbox>
  <duet-checkbox label="Option 3"></duet-checkbox>
</duet-fieldset>
Open in new window 
<duet-fieldset
  label="Travel dates"
  caption="This is a caption lorem ipsum blah blah dulce est decorum est, pro patri amor"
>
  <duet-tooltip slot="tooltip">Lorem ipsum</duet-tooltip>
  <duet-date-picker label="Departure date"></duet-date-picker>
  <duet-date-picker label="Return date"></duet-date-picker>
</duet-fieldset>

Properties #

Property Attribute Description Type Default
accessibleLiveError accessible-live-error The aria-live attribute for the error message. When the input is validated on blur, use "off", as using "polite" or "assertive" makes the screen reader read the error message twice. When the input is validated on submit, use "polite", as "off" would leave the messages unread by screen readers. Use "assertive" only in those rare cases when "polite" would leave the error message unread by screen readers. "assertive" | "off" | "polite" "polite"
caption caption Additional caption to show next to the label. string undefined
error error An error message to be shown next to the label. string undefined
label (required) label Label/legend displayed for the fieldset. string undefined
labelHeadingLevel label-heading-level Heading level for the label in the legend element. This is only used to give screen readers better logical structure. This does not affect visual appearance. "h1" | "h2" | "h3" | "h4" | "h5" | "h6" "h3"
labelHidden label-hidden Visually hide the label, but still show it to screen readers. boolean false
margin margin Controls the margin of the component. "auto" | "none" "auto"
theme theme Theme of the fieldset. "" | "default" | "turva" ""
