Fieldset
A labeled, vertically-stacked group of form controls.
Real use · profile group
Disabled cascades to every control
Using Fieldset
Silica ships one design system through three paths. They share a class vocabulary but are not interchangeable — pick the one that matches what you are building.
Plain HTML — CSS classes
The Tailwind v4 plugin. Works in any framework or none — Rails, Django, PHP, Go, a static file. This path is complete for Fieldset — it needs no JavaScript, so the classes below are the whole story.
/* in your CSS */
@import "tailwindcss";
@plugin "@wizeworks/silicaui";Root class fieldset, with 2 modifiers:
.fieldset.fieldset-label.fieldset-legend
React
Typed components over those same classes, with behavior and accessibility from Base UI.
npm i @wizeworks/silicaui-reactimport { Fieldset } from "@wizeworks/silicaui-react";Source of the demo above
The exact file that renders the examples above, so it can never drift from them. It imports a few of this site’s own layout helpers (../lib/…), so read it for the component calls rather than copying it whole.
Show source
import { Fieldset, FieldsetLegend, FieldsetLabel, Input } from "@wizeworks/silicaui-react";
import { Section } from "../lib/Section";
export function FieldsetDemo() {
return (
<>
<Section title="Real use · profile group">
<Fieldset className="max-w-sm">
<FieldsetLegend>Profile</FieldsetLegend>
<Input placeholder="Full name" />
<FieldsetLabel>Your full legal name.</FieldsetLabel>
</Fieldset>
</Section>
<Section title="Disabled cascades to every control">
<Fieldset disabled className="max-w-sm">
<FieldsetLegend>Billing (locked)</FieldsetLegend>
<Input placeholder="Card number" />
<FieldsetLabel>Contact support to change billing.</FieldsetLabel>
</Fieldset>
</Section>
</>
);
}Vanilla — node tree to HTML
Fieldset — lowers to <fieldset>, holding its children. Build a node tree, project it with toHtml(), and let the zero-dependency runtime hydrate it. This is the path for generated or user-authored documents — a site builder, CMS output, a static export.
npm i @wizeworks/silicaui-html @wizeworks/silicaui-behaviorsimport { atom, toHtml } from "@wizeworks/silicaui-html";
const node = atom("Fieldset", "fieldset", { /* props */ }, [/* children */]);
const markup = toHtml(node);Styling on this path is the class string in the second argument — the same classes as the Plain HTML section above. There is no color prop here; write "fieldset fieldset-primary" rather than passing a colour as a prop.
- Takes children
- yes
- Hydrated by
- nothing — this one is static markup
The full API for Fieldset, on every path, is available through the Silica MCP server.
