Implementing a multi-step form in Vue.js involves creating a component for each step and managing the form state to navigate between the steps. Here's a basic example to get you started:

  1. Create a Vue component for each form step:

    html
    <!-- Step1.vue --> <template> <div> <h2>Step 1</h2> <!-- Your form fields for step 1 --> <button @click="nextStep">Next</button> </div> </template> <script> export default { methods: { nextStep() { this.$emit('next', 2); // Emit an event to move to the next step }, }, }; </script>
    html
    <!-- Step2.vue --> <template> <div> <h2>Step 2</h2> <!-- Your form fields for step 2 --> <button @click="prevStep">Previous</button> <button @click="nextStep">Next</button> </div> </template> <script> export default { methods: { prevStep() { this.$emit('prev', 1); // Emit an event to move to the previous step }, nextStep() { this.$emit('next', 3); // Emit an event to move to the next step }, }, }; </script>
    html
    <!-- Step3.vue --> <template> <div> <h2>Step 3</h2> <!-- Your form fields for step 3 --> <button @click="prevStep">Previous</button> <button @click="submitForm">Submit</button> </div> </template> <script> export default { methods: { prevStep() { this.$emit('prev', 2); // Emit an event to move to the previous step }, submitForm() { // Handle form submission logic }, }, }; </script>
  2. Create the main form component that manages the steps:

    html
    <!-- MainForm.vue --> <template> <div> <component :is="currentStepComponent" @next="nextStep" @prev="prevStep" /> </div> </template> <script> import Step1 from './Step1.vue'; import Step2 from './Step2.vue'; import Step3 from './Step3.vue'; export default { data() { return { currentStep: 1, }; }, computed: { currentStepComponent() { // Dynamically return the component based on the current step switch (this.currentStep) { case 1: return Step1; case 2: return Step2; case 3: return Step3; default: return null; } }, }, methods: { nextStep(nextStep) { this.currentStep = nextStep; }, prevStep(prevStep) { this.currentStep = prevStep; }, }, }; </script>
  3. Use the main form component in your app:

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

This is a basic example, and you can customize it based on your specific form requirements. The key is to emit events from child components to inform the parent component about the step changes.
