Integrate with VitePress

Configure VitePress config

// .vitepress/config.js
import { defineConfig } from 'vitepress'
import multipleChoicePlugin from 'markdown-it-multiple-choice'

export default defineConfig({
  markdown: {
    config: (md) => {
      md.use(multipleChoicePlugin)
    }
  },
  vite: {
    ssr: {
      noExternal: ['markdown-it-multiple-choice']
    }
  }
})

Step 3: Setup theme

Create .vitepress/theme/index.js:

import DefaultTheme from 'vitepress/theme'
import { onMounted } from 'vue'
import { setupMultipleChoice } from 'markdown-it-multiple-choice'
import 'markdown-it-multiple-choice/style.css'

export default {
  extends: DefaultTheme,
  setup() {
    onMounted(() => {
      setupMultipleChoice();
    });
  }
}

Markdown Syntax

The plugin recognizes a special syntax for multiple choice questions:

[?] Your question goes here?
[ ] Wrong answer option
[x] Correct answer option (marked with 'x')
[ ] Another wrong answer option
[ ] Yet another wrong answer option

Syntax Rules

• Question: Start with [?] followed by your question text
• Correct Answer: Use [x] to mark the correct option
• Wrong Answers: Use [ ] (empty brackets) for incorrect options
• Multiple Questions: Separate questions with blank lines
