Vue Dynamic V-model Within V-for

I have the following fieldsets containing checkboxes:

Copy

and you should loop using v-for like :

       <fieldset v-for="(filters, key,index) in availableFilters">

where the filters represents the value, key represents the key like level and ìndex represents the index such 0, using the key item we could access selected like selected[key] so we could bind the checkbox to that property easily.

Full example

new Vue({
  el: '#app',

  data() {
    return {
      selected: {
        level: [],
        subject: [],
        delivery: []
      },
      availableFilters: {
        level: {
          "UG": 12,
          "PG": 12,
        },
        subject: {

        }
      }
    }

  }
 
});
