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 #
<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>
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" | "span" | "span" |
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" | "" |
Slots #
Slot | Description |
