+# Merge Print/Export Buttons Into Dropdown 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:** Replace the two separate "打印整册" / "导出 MD" toolbar buttons with a single "导出 ▾" button that opens a dropdown menu offering both actions, and extract the dropdown logic that's now used by two buttons into a shared `ToolbarMenuButton.vue` component.
+
+**Architecture:** Extract `ToolbarMenuButton.vue` — a generic dropdown wrapper that owns open/close state, outside-click/Escape dismissal, and `disabled` handling, exposing menu items via a scoped default slot (`{ close }`). Refactor the existing `GenerateMenuButton.vue` to be a thin wrapper around it (no behavior change, same public DOM contract). Add a new `ExportMenuButton.vue`, also a thin wrapper, for "打印整册"/"导出 MD". `WorkspaceToolbar.vue` swaps its two standalone buttons for `ExportMenuButton`; `WorkspaceView.vue` requires no changes.
+
+**Tech Stack:** Vue 3 (`<script setup lang="ts">`), Vitest + `@vue/test-utils`, plain CSS in `src/style.css` (no UI component library).
+
+## Global Constraints
+
+- Button label for the merged print/export button is exactly "导出 ▾".
+- Clicking the main button only toggles the dropdown; it never directly fires `print` or `export`.
+- The two menu item buttons keep `data-testid="print"` and `data-testid="export"`.
+- The new toggle button uses `data-testid="export-menu-toggle"`.
+- The merged button is disabled as a whole (native `disabled` attribute) when `lessonCount === 0` — matching the existing per-button disabled condition on "打印整册"/"导出 MD".
+- `GenerateMenuButton.vue`'s public DOM contract (testids `generate-menu-toggle`, `generate`, `batch-generate`, label "生成教案 ▾", events `generate`/`batchGenerate`) must NOT change as an observable behavior — internal implementation may change.
+- `WorkspaceToolbar.vue`'s `defineEmits` block and `WorkspaceView.vue`'s event listeners must NOT change.
+- Reuse existing CSS design tokens only (`var(--line)`, `var(--radius-md)`, `var(--green-100)`, `var(--green-700)`) — no new color/radius values.
+- No changes to generation/print/export business logic, `BatchGenerateDialog.vue`, or `GenerateLessonDialog.vue`.
+
+---
+
+### Task 1: Create `ToolbarMenuButton.vue` with tests
+
+**Files:**
+- Create: `src/components/ToolbarMenuButton.vue`
+- Create: `src/components/ToolbarMenuButton.test.ts`
+
+**Interfaces:**
+- Produces: `ToolbarMenuButton` component with:
+  ```ts
+  defineProps<{
+    label: string
+    toggleTestid: string
+    disabled?: boolean
+  }>()
+  ```
+  No emits — it has no domain knowledge of what actions exist. Default slot receives scope `{ close: () => void }`. Consumers render their own `<li>` menu items inside the slot and call `close()` after emitting their own event.
+- DOM contract later tasks rely on:
+  - Toggle button: `button[:data-testid="toggleTestid"]` (the literal value passed via the `toggleTestid` prop)
+  - Root wrapper: `div.toolbar-menu`
+  - Menu list (only in DOM while open): `ul.toolbar-menu-list`, rendered via `<slot :close="close" />` inside it
+
+- [ ] **Step 1: Write the failing tests**
+
+Create `src/components/ToolbarMenuButton.test.ts`:
+
+```ts
+import { mount } from '@vue/test-utils'
+import { describe, expect, it } from 'vitest'
+import ToolbarMenuButton from './ToolbarMenuButton.vue'
+
+function mountMenu(props: { label: string; toggleTestid: string; disabled?: boolean }) {
+  return mount(ToolbarMenuButton, {
+    props,
+    attachTo: document.body,
+    slots: {
+      default: `<template #default="{ close }">
+        <li role="menuitem"><button data-testid="item-a" @click="close">Item A</button></li>
+        <li role="menuitem"><button data-testid="item-b" @click="close">Item B</button></li>
+      </template>`,
+    },
+  })
+}

+describe('ToolbarMenuButton', () => {
+  it('renders the toggle button with the given label and closed menu by default', () => {
+    const wrapper = mountMenu({ label: '导出 ▾', toggleTestid: 'export-menu-toggle' })
+    expect(wrapper.get('button[data-testid="export-menu-toggle"]').text()).toBe('导出 ▾')
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(false)
+    wrapper.unmount()
+  })
+
+  it('opens the menu when the toggle button is clicked', async () => {

+    expect(wrapper.get('[data-testid="item-a"]').isVisible()).toBe(true)
+    expect(wrapper.get('[data-testid="item-b"]').isVisible()).toBe(true)
+    wrapper.unmount()
+  })
+
+  it('closes the menu when a slot item calls close', async () => {
+    const wrapper = mountMenu({ label: '导出 ▾', toggleTestid: 'export-menu-toggle' })
+    await wrapper.get('button[data-testid="export-menu-toggle"]').trigger('click')

+
+  it('closes the menu when clicking outside the component', async () => {
+    const wrapper = mountMenu({ label: '导出 ▾', toggleTestid: 'export-menu-toggle' })
+    await wrapper.get('button[data-testid="export-menu-toggle"]').trigger('click')
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(true)
+
+    document.body.click()
+    await wrapper.vm.$nextTick()
+
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(false)
+    wrapper.unmount()
+  })
+
+  it('closes the menu when Escape is pressed', async () => {
+    const wrapper = mountMenu({ label: '导出 ▾', toggleTestid: 'export-menu-toggle' })
+    await wrapper.get('button[data-testid="export-menu-toggle"]').trigger('click')
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(true)
+
+    await wrapper.get('div.toolbar-menu').trigger('keydown', { key: 'Escape' })
+
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(false)
+    wrapper.unmount()
+  })
+
+  it('disables the toggle button and never opens the menu when disabled is true', async () => {
+    const wrapper = mountMenu({ label: '导出 ▾', toggleTestid: 'export-menu-toggle', disabled: true })

+    await wrapper.get('button[data-testid="export-menu-toggle"]').trigger('click')
+    expect(wrapper.find('[data-testid="item-a"]').exists()).toBe(false)
+    wrapper.unmount()
+  })
+})
+```
+
+- [ ] **Step 2: Run tests to verify they fail**
+
+Run: `npx vitest run src/components/ToolbarMenuButton.test.ts`
+Expected: FAIL — `Failed to resolve import "./ToolbarMenuButton.vue"` (file doesn't exist yet).
+
+- [ ] **Step 3: Write the component implementation**
+
+Create `src/components/ToolbarMenuButton.vue`:
+
+```vue
+<script setup lang="ts">
+import { onMounted, onUnmounted, ref } from 'vue'
+
+defineProps<{
+  label: string
+  toggleTestid: string
+  disabled?: boolean
+}>()
+
+const open = ref(false)
+const rootRef = ref<HTMLElement | null>(null)
+
+function toggle(): void {
+  open.value = !open.value
+}
+
+function close(): void {
+  open.value = false
+}
+
+function handleDocumentClick(event: MouseEvent): void {
+  if (!rootRef.value) return
+  if (!rootRef.value.contains(event.target as Node)) {
+    close()
+  }
+}
+
+function handleKeydown(event: KeyboardEvent): void {
+  if (event.key === 'Escape') {
+    close()
+  }
+}
+
+onMounted(() => {
+  document.addEventListener('click', handleDocumentClick)
+})
+
+onUnmounted(() => {
+  document.removeEventListener('click', handleDocumentClick)
+})
+</script>
+
+<template>
+  <div ref="rootRef" class="toolbar-menu" @keydown="handleKeydown">
+    <button
+      type="button"
+      :data-testid="toggleTestid"
+      :disabled="disabled"
+      :aria-expanded="open"
+      @click.stop="toggle"
+    >
+      {{ label }}
+    </button>
+    <ul v-if="open" class="toolbar-menu-list" role="menu">
+      <slot :close="close" />
+    </ul>
+  </div>
+</template>
+```
+
+Note: a native `disabled` button never dispatches `click` events, so `toggle()` cannot run while `disabled` is true — no extra guard needed in `toggle()` itself.
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+Run: `npx vitest run src/components/ToolbarMenuButton.test.ts`
+Expected: PASS (6 tests).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/components/ToolbarMenuButton.vue src/components/ToolbarMenuButton.test.ts
+git commit -m "feat: add generic ToolbarMenuButton dropdown component"
+```
+
+---
+
+### Task 2: Refactor `GenerateMenuButton.vue` to use `ToolbarMenuButton`
+
+**Files:**
+- Modify: `src/components/GenerateMenuButton.vue` (full rewrite, ~21 lines)
+- Modify: `src/components/GenerateMenuButton.test.ts:54` (one assertion)
+
+**Interfaces:**
+- Consumes: `ToolbarMenuButton` from Task 1 — props `label`, `toggleTestid`, `disabled?`; default slot scope `{ close }`.
+- Produces: `GenerateMenuButton` keeps emitting `generate` / `batchGenerate` exactly as before, with identical DOM contract (`generate-menu-toggle`, `generate`, `batch-generate`, label "生成教案 ▾"). No prior consumer of `GenerateMenuButton` (i.e. `WorkspaceToolbar.vue`) needs to change.
+
+This task is a pure refactor: the existing `GenerateMenuButton.test.ts` (6 tests, unchanged behavior asserted through testids) must still pass except for the one assertion that inspects the internal root class name.
+
+- [ ] **Step 1: Update the one test assertion that touches internal implementation**
+
+In `src/components/GenerateMenuButton.test.ts`, line 54 currently reads:
+
+```ts
+    await wrapper.get('div.generate-menu').trigger('keydown', { key: 'Escape' })
+```
+
+Change it to:
+
+```ts
+    await wrapper.get('div.toolbar-menu').trigger('keydown', { key: 'Escape' })
+```
+
+- [ ] **Step 2: Run the existing test to verify it fails for the expected reason**
+
+Run: `npx vitest run src/components/GenerateMenuButton.test.ts`
+Expected: FAIL on `closes the menu when Escape is pressed` — `div.toolbar-menu` does not exist yet (component still renders `div.generate-menu`). The other 5 tests still pass at this point since the component hasn't changed yet.
+
+- [ ] **Step 3: Rewrite the component to wrap `ToolbarMenuButton`**
+
+Replace the full contents of `src/components/GenerateMenuButton.vue` with:
+
+```vue
+<script setup lang="ts">
+import ToolbarMenuButton from './ToolbarMenuButton.vue'
+
+const emit = defineEmits<{
+  generate: []
+  batchGenerate: []
+}>()
+</script>
+
+<template>
+  <ToolbarMenuButton label="生成教案 ▾" toggle-testid="generate-menu-toggle">
+    <template #default="{ close }">
+      <li role="menuitem">
+        <button
+          type="button"
+          data-testid="batch-generate"
+          @click="
+            emit('batchGenerate')
+            close()
+          "
+        >
+          批量生成
+        </button>
+      </li>
+      <li role="menuitem">
+        <button
+          type="button"
+          data-testid="generate"
+          @click="
+            emit('generate')
+            close()
+          "
+        >
+          生成一篇
+        </button>
+      </li>
+    </template>
+  </ToolbarMenuButton>
+</template>
+```
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+Run: `npx vitest run src/components/GenerateMenuButton.test.ts`
+Expected: PASS (6 tests) — identical behavior, now backed by `ToolbarMenuButton`.
+
+Also run the consumers to confirm no regression:
+Run: `npx vitest run src/components/WorkspaceToolbar.test.ts src/components/WorkspaceView.test.ts`
+Expected: same pass/fail counts as before this task (the 3 pre-existing unrelated `WorkspaceView.test.ts` failures about file-upload placeholder text and batch-generate concurrency ordering are unaffected; `WorkspaceToolbar.test.ts` fully passes).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/components/GenerateMenuButton.vue src/components/GenerateMenuButton.test.ts
+git commit -m "refactor: rebuild GenerateMenuButton on top of ToolbarMenuButton"

+- Produces: `ExportMenuButton` component:

+  defineEmits<{ print: []; export: [] }>()
+  ```
+  DOM contract: toggle `button[data-testid="export-menu-toggle"]` with label "导出 ▾"; menu items `button[data-testid="print"]` ("打印整册") and `button[data-testid="export"]` ("导出 MD"), only present while the dropdown is open.

+
+### Task 4: Wire `ExportMenuButton` into `WorkspaceToolbar.vue`
+
+**Files:**
+- Modify: `src/components/WorkspaceToolbar.vue`
+- Modify: `src/components/WorkspaceToolbar.test.ts`
+- Modify: `src/components/WorkspaceView.test.ts:207`
+
+**Interfaces:**
+- Consumes: `ExportMenuButton` from Task 3 — props `disabled?`, events `print`/`export`, testids `export-menu-toggle`/`print`/`export`.
+- Produces: `WorkspaceToolbar` keeps emitting `print` and `export` exactly as before — no change to its own `defineEmits` block or to how `WorkspaceView.vue` listens to it.
+
+- [ ] **Step 1: Write the failing tests**
+
+In `src/components/WorkspaceToolbar.test.ts`, replace the `disables print, export and clear when there are no lessons` test (currently the last test in the file, asserting on `data-testid="print"` / `"export"` directly) with:
+
+```ts
+  it('disables the export menu toggle and clear button when there are no lessons', () => {
+    const wrapper = mountToolbar(0)
+    expect(
+      wrapper.get('button[data-testid="export-menu-toggle"]').attributes('disabled'),

+    expect(wrapper.emitted('export')).toHaveLength(1)
+  })

+
+(Keep every other existing test in the file unchanged.)
+
+In `src/components/WorkspaceView.test.ts`, line 207 currently reads:
+
+```ts
+    await wrapper.get('[data-testid="export"]').trigger('click')
+```
+
+Change it to:
+
+```ts
+    await wrapper.get('[data-testid="export-menu-toggle"]').trigger('click')
+    await wrapper.get('[data-testid="export"]').trigger('click')
+```
+
+- [ ] **Step 2: Run tests to verify they fail**
+
+Run: `npx vitest run src/components/WorkspaceToolbar.test.ts src/components/WorkspaceView.test.ts`
+Expected: FAIL — `export-menu-toggle` testid not found (toolbar still has the old two standalone buttons).
+
+- [ ] **Step 3: Update the toolbar template**
+
+In `src/components/WorkspaceToolbar.vue`, add the import in `<script setup>` alongside the existing `GenerateMenuButton` import:
+
+```ts
+import ExportMenuButton from './ExportMenuButton.vue'
+```
+
+Replace the two lines:
+
+```vue
+    <button type="button" data-testid="print" :disabled="lessonCount === 0" @click="$emit('print')">打印整册</button>
+    <button type="button" data-testid="export" :disabled="lessonCount === 0" @click="$emit('export')">导出 MD</button>
+```
+
+with:
+
+```vue
+    <ExportMenuButton :disabled="lessonCount === 0" @print="$emit('print')" @export="$emit('export')" />
+```
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+Run: `npx vitest run src/components/WorkspaceToolbar.test.ts src/components/WorkspaceView.test.ts`
+Expected: PASS for `WorkspaceToolbar.test.ts` (all tests); `WorkspaceView.test.ts` shows the same pre-existing 3 unrelated failures as before this task (file-upload placeholder text, batch-generate concurrency ordering) and no new failures.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/components/WorkspaceToolbar.vue src/components/WorkspaceToolbar.test.ts src/components/WorkspaceView.test.ts
+git commit -m "feat: merge print/export buttons into a single dropdown in WorkspaceToolbar"

+
+### Task 5: Rename CSS classes from `generate-menu` to generic `toolbar-menu`
+
+**Files:**
+- Modify: `src/style.css:273-307` (the three `.generate-menu*` rules)
+- Modify: `src/style.css:778-780` (the mobile media-query rule)
+
+**Interfaces:**
+- Consumes: class names `toolbar-menu` / `toolbar-menu-list` already rendered by `ToolbarMenuButton.vue` (Task 1).
+- Produces: a single shared style block used by both `GenerateMenuButton` and `ExportMenuButton` — no per-button duplication.
+
+- [ ] **Step 1: Rename the dropdown style block**
+
+In `src/style.css`, replace lines 273-307:

+- [ ] **Step 2: Rename the mobile media-query rule**
+
+In `src/style.css`, inside the `@media (max-width: 600px)` block, replace:
+
+```css
+  .workspace-toolbar .generate-menu {
+    flex: 0 0 auto;
+  }
+```
+
+with:
+
+```css
+  .workspace-toolbar .toolbar-menu {
+    flex: 0 0 auto;
+  }
+```
+
+- [ ] **Step 3: Run the full test suite to confirm no regressions**
+
+Run: `npx vitest run`
+Expected: PASS for all suites except the 5 pre-existing, unrelated failures (3 in `WorkspaceView.test.ts` about file-upload placeholder text and batch-generate concurrency ordering, 2 in `useTeachingBook.test.ts` about `store.importFiles`) — CSS changes don't affect Vitest/jsdom assertions; this is a safety check that nothing else broke.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/style.css
+git commit -m "style: rename generate-menu CSS classes to generic toolbar-menu"
+```
