formOptions: {
  validateAfterChanged: true
}

Installation

npm install vfg-field-array

vfg-field-array can be used as a module in both CommonJS and ES modular environments.

When in non-modular environment, vfg-field-array will register all the components to vue by itself.

ES6

//
// You can register a component manually
//
import { FieldArray } from 'vfg-field-array';

export default {
  ...
  components: {
    FieldArray
  },
  ...
};

//
// or register the whole module with vue
//
import ModuleLibrary from 'vfg-field-array';

// Install this library
Vue.use(ModuleLibrary);

CommonJS

//
// You can register a component manually
//
var Vue = require('vue');
var ModuleLibrary = require('vfg-field-array');

var YourComponent = Vue.extend({
  ...
  components: {
    'field-array': ModuleLibrary.FieldArray
  },
  ...
});

//
// or register the whole module with vue
//
var Vue = require('vue');
var ModuleLibrary = require('vfg-field-array');

// Install this library
Vue.use(ModuleLibrary);

Browser

<script src="path/to/vue/vue.min.js"></script>
<script src="path/to/vfg-field-array/dist/vfg-field-array.min.js"></script>
<!-- Components are registered globally -->

After that, you can use it with Vue Form Generator:

  schema: {
    fields: [
      {
        type: "array",
        label: "My array",
        model: "myArray"
      }
    ]
  }
