Gildas Garcia bfb0737d14 Fix to ensure labels, descriptions and validation errors are correctly linked to their inputs (#50080)
## Problem

`FormItemLayout` does not correctly binds inputs descriptions and
validation messages to their inputs. This is because the input ids are
generated and not correctly propagated to the `FormMessage` and
`FormDescription` components. Besides, we still pass `name` or `id`
directly to the inputs or `FormItemLayout` in some places.

## Solution

- Fix `FormItemLayout` to correctly binds inputs descriptions and
validation messages to their inputs
- Fix incorrect usages
- Fix Design System documentation

## How to test

The issue is visible in production:
- Open https://supabase.com/design-system/docs/ui-patterns/forms
- Open the devtool and check the labels `for`, the description `id` and
the input `id` or `aria-describedby` attributes. You'll see they often
don't match

Do the same on staging:
- Open
https://design-system-git-fix-a11y-form-input-descriptions-supabase.vercel.app/design-system/docs/ui-patterns/forms
- Open the devtool and check the labels `for`, the description `id` and
the input `id` or `aria-describedby` attributes. They now match

Dashboard fixes:
-
https://studio-staging-git-fix-a11y-form-input-descriptions-supabase.vercel.app/dashboard/account/tokens:
_Expires in_ select button is now correctly linked to its label
-
https://studio-staging-git-fix-a11y-form-input-descriptions-supabase.vercel.app/dashboard/account/me:
the switches are now correctly linked to their label
- In Database/Indexes: the select buttons when creating an index are now
correctly linked to their label
- All other changes are the same things

Supabase Design System

Design resources for building consistent user experiences at Supabase.

Getting started

First, make a copy of .env.local.example and name it env.local. Then install any required packages and start the development server:

cd apps/design-system
pnpm i
pnpm dev

The dev command generates __registry__, then runs the Next.js development server and Contentlayer together. That is the recommended workflow.

Alternative commands

You can also run the development server and content watcher separately. Generate the registry first, because dev:next and dev:content do not:

pnpm generate:registry

# Run only the Next.js development server
pnpm dev:next

# Run only the content watcher (in a separate terminal shell)
pnpm dev:content

From the repo root, pnpm dev:design-system runs the same dev script, so it also generates __registry__. If you split the watchers from the root, generate first:

pnpm --filter=design-system generate:registry
pnpm --filter=design-system dev:next
pnpm --filter=design-system dev:content

Open http://localhost:3003 in your browser to see the result.

Watching for MDX changes

The dev command watches MDX files and hot-reloads them. If you are running pnpm dev:next on its own, also run pnpm dev:content in another terminal.

Adding components

The design system references components rather than housing them. That distinction matters: everything below is about documenting components, not implementing them. Add or edit the components themselves in one of these two places:

After you add or remove documented components, update these source files:

  • config/docs.ts: list of components in the sidebar
  • content/docs: the component documentation
  • registry/examples.ts: example components
  • registry/fragments.ts: fragment components
  • registry/charts.ts: chart components
  • registry/copy-writing.ts: copywriting examples
  • registry/default/example/*: the example component implementations
  • registry/default/block/*: chart block implementations, when you add a chart

Do not edit __registry__. pnpm dev, pnpm typecheck, and pnpm build generate it from the files above, and it is gitignored. If you add registry entries while the app is already running, regenerate it:

cd apps/design-system
pnpm generate:registry
