Collection

List or grid that switches surfaces from intent: pending load, empty data, or error. You supply items and state; Collection picks skeleton / empty / error UI.

Basic

<script setup lang="ts">
import { Collection } from 'pomikit-ui'

type Row = { id: string; name: string }

defineProps<{
  items: Row[]
  pending: boolean
  error: unknown
}>()
</script>

<template>
  <Collection
    :items="items"
    :pending="pending"
    :error="error"
    layout="stack"
    empty-title="No projects yet"
    empty-description="Create your first project to get started."
    @retry="$emit('retry')"
  >
    <template #item="{ item }">
      {{ item.name }}
    </template>
  </Collection>
</template>

Intent matrix

State	Behavior
pending + no items	Skeleton placeholders (skeletonCount)
pending + existing items	Keep list; refresh intent
empty items	EmptyState (emptyTitle / emptyDescription)
error set	ErrorState + retry emit

Layout

• layout: 'stack' | 'grid'
• columns: grid column count (default 3)

Prefer these data intents over wiring Skeleton / EmptyState / ErrorState by hand, unless you need a custom composition outside lists.
