Q: What is a shadcn label?

A shadcn label is the styled ` ` element you pair with form controls — Input, Checkbox, Switch, RadioGroup. It's built on Radix UI's Label primitive (which extends the native ` ` with proper htmlFor wiring, peer-disabled state propagation, and click-to-focus for any inner control) and styled with shadcn/ui + Tailwind. Each example shows a different way to compose label + control.

Q: How do I show a required indicator (asterisk) on a label?

Two conventions. (1) Mark required: append ` * ` after the label text. Pair with a small note at the top of the form: "* required". (2) Mark optional (the inverse): append ` (optional) ` after labels for optional fields. The inverse approach reads cleaner when most fields are required.

Question 1

What is a shadcn label?

Accepted Answer

A shadcn label is the styled `` element you pair with form controls — Input, Checkbox, Switch, RadioGroup. It's built on Radix UI's Label primitive (which extends the native `` with proper htmlFor wiring, peer-disabled state propagation, and click-to-focus for any inner control) and styled with shadcn/ui + Tailwind. Each example shows a different way to compose label + control.

Question 2

Are these label examples free?

Accepted Answer

Yes, every label example on shadcn.io is free for personal and commercial use — no attribution requirement, no runtime dependency, no gating.

Question 3

Why use Radix Label instead of a plain <label>?

Accepted Answer

Two reasons. (1) The Radix Label clicks BLOCK click events from bubbling to its parent, which prevents the click-on-label-also-clicks-the-card bug when the label is nested inside a clickable wrapper. (2) The Label automatically inherits the disabled state from its associated control via the `peer-disabled:` modifier — when the input is disabled, the label dims to match. Native `<label>` does neither.

Question 4

When should I use a Label versus inline placeholder text?

Accepted Answer

Always use a Label for form fields. Placeholder text disappears the moment the user starts typing — so it can't double as the field's name. Studies consistently show form completion rates rise when labels stay visible. Use placeholder for FORMAT hints ("e.g. john@example.com") not for the field's identity. The shadcn Field primitive enforces this pattern (Label + Input + optional Description + optional placeholder).

Question 5

How do I associate a label with an input?

Accepted Answer

Pass `htmlFor="email"` to Label and `id="email"` to the matching Input. Clicking the label focuses the input. shadcn's Field primitive does this for you automatically — wrap Label + Input in `<Field>` and the IDs are wired via React context. For custom layouts where you can't use Field, write the htmlFor / id pair manually.

Question 6

How do I show a required indicator (asterisk) on a label?

Accepted Answer

Two conventions. (1) Mark required: append `*` after the label text. Pair with a small note at the top of the form: "* required". (2) Mark optional (the inverse): append `(optional)` after labels for optional fields. The inverse approach reads cleaner when most fields are required.

Question 7

How do I label a Checkbox or Switch (where the label sits beside the control)?

Accepted Answer

Wrap the Checkbox + Label in a horizontal flex container (`flex items-center gap-2`). Use `<label className="flex items-center gap-2">` so the entire row becomes the click target — clicking the text toggles the checkbox. This is the canonical pattern; users expect to click anywhere in the row, not just the tiny checkbox square.

Question 8

How do I install a label example?

Accepted Answer

Run the `npx shadcn@latest add` command shown under the Installation heading. The CLI copies the example's TSX source into `components/examples/label/…`, plus the shadcn/ui Label primitive (and its Radix dependency) if you don't already have it.

Question 9

How do I size or restyle the label?

Accepted Answer

Pass className overrides — `text-sm font-medium` is the default. For section headings inside settings pages, scale to `text-base font-semibold`. For dense compact forms, drop to `text-xs uppercase tracking-wide text-muted-foreground` for an eyebrow-style label. Match the style across the form for visual consistency.

Question 10

How do I show a label tooltip with help text?

Accepted Answer

Render the Label, then a small InfoIcon next to it wrapped in a Tooltip. The tooltip shows on hover with the help text. Common pattern for technical fields where extra context helps but a Description below would clutter the form. Keep tooltip text under 1 sentence; longer help belongs in a description.

Question 11

Which libraries do label examples depend on?

Accepted Answer

Radix UI Label (the primitive — htmlFor handling, peer-disabled propagation, click event isolation), shadcn/ui Label (the styled wrapper generated into your project), Tailwind CSS. For tooltip-on-label examples, shadcn/ui Tooltip + Lucide Info icon. React 19 baseline.

Question 12

Are label examples accessible for keyboard and screen reader users?

Accepted Answer

Yes. The Radix Label uses native `<label>` semantics so screen readers automatically associate it with the linked input. Clicking the label focuses the input (native behavior, preserved). Required state and validation errors flow from the input's `aria-required` / `aria-invalid` / `aria-describedby` attributes — the Label is just the visible name.

Question 13

Can I use these label examples with React Server Components?

Accepted Answer

Yes — Label is pure render with no client state. It works cleanly as a Server Component. The catch: Label's click-handling behavior runs in the browser, but rendering happens on the server. Hybrid pages (server-rendered form skeleton + client-side input state) work without special wiring.
