How to implement a dynamic questionnaire builder in Vue.js

Implementing a dynamic questionnaire builder in Vue.js involves creating a user interface where users can add, edit, and remove questions dynamically. Here's a basic example to get you started:

1. Setup Vue Project: Make sure you have Vue.js installed. You can set up a new Vue project using Vue CLI:

   bashCopy code
   vue create dynamic-questionnaire-builder
   

2. Create Components: Create Vue components for the questionnaire builder and individual question items.

   htmlCopy code
   <!-- QuestionnaireBuilder.vue -->
   <template>
     <div>
       <button @click="addQuestion">Add Question</button>
       <div v-for="(question, index) in questions" :key="index">
         <Question :question="question" @remove="removeQuestion(index)" />
       </div>
     </div>
   </template>
   
   <script>
   import Question from './Question.vue';
   
   export default {
     components: {
       Question,
     },
     data() {
       return {
         questions: [],
       };
     },
     methods: {
       addQuestion() {
         this.questions.push({ text: '', type: 'text' });
       },
       removeQuestion(index) {
         this.questions.splice(index, 1);
       },
     },
   };
   </script>
   

   htmlCopy code
   <!-- Question.vue -->
   <template>
     <div>
       <input v-model="question.text" placeholder="Enter question text" />
       <select v-model="question.type">
         <option value="text">Text</option>
         <option value="radio">Multiple Choice</option>
         <option value="checkbox">Checkbox</option>
       </select>
       <button @click="$emit('remove')">Remove</button>
     </div>
   </template>
   
   <script>
   export default {
     props: ['question'],
   };
   </script>
   

3. Style Components: Style the components as per your design requirements.

4. Integrate in App: Integrate the QuestionnaireBuilder component in your main App.vue file or any other parent component.

   htmlCopy code
   <!-- App.vue -->
   <template>
     <div id="app">
       <QuestionnaireBuilder />
     </div>
   </template>
   
   <script>
   import QuestionnaireBuilder from './components/QuestionnaireBuilder.vue';
   
   export default {
     components: {
       QuestionnaireBuilder,
     },
   };
   </script>
   

5. Run the Application: Finally, run your Vue.js application:

   bashCopy code
   npm run serve
   

With this setup, users can dynamically add questions to the questionnaire by clicking the "Add Question" button and remove them by clicking the "Remove" button on each question. They can also edit the question text and select the question type from a dropdown menu. You can further enhance this implementation by adding validation, saving/loading functionality, etc., based on your requirements.
