# TabList Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Créer un composant `MalioTabList` — barre d'onglets horizontale avec icônes, gestion show/hide des panneaux via slots nommés, pattern contrôlé/non-contrôlé.

**Architecture:** Composant unique `TabList.vue` dans `app/components/malio/tab/`. Props `tabs` (tableau `{key, label, icon?}`) + `modelValue` (clé active). Slots nommés par `tab.key` pour le contenu des panneaux. Couleur active `text-m-primary`, inactif `text-m-primary/50` (50% opacité). Bordure active `border-m-primary`, bordure commune `border-m-border`.

**Tech Stack:** Vue 3 Composition API, TypeScript, Tailwind CSS, @iconify/vue, Vitest + @vue/test-utils

**Ticket:** MUI-11

## Props détaillées

### tabs

- Type: `Array<{ key: string; label: string; icon?: string }>`
- Requis: oui
- Description: Définit les onglets. Chaque entrée correspond à un slot nommé par `key`.

### id

- Type: `string`
- Description: Préfixe pour les IDs d'accessibilité. Auto-généré si absent.

---

## Slots

Un slot nommé par `tab.key` pour chaque onglet. Le contenu du slot est affiché/masqué automatiquement.

```html
<MalioTabList :tabs="[{ key: 'foo', label: 'Foo' }]">
  <template #foo>Contenu de Foo</template>
</MalioTabList>
```

---

## Accessibilité

- `role="tablist"` sur le conteneur
- `role="tab"` avec `aria-selected`, `aria-controls`, `tabindex` sur chaque bouton
- `role="tabpanel"` avec `aria-labelledby` sur chaque panneau
