Vue Js checkbox model from json data

Question

I have a product search page with filters based on selected Category.

Depending on selected category by user I get following response from api

  "customFields":{
     "select":{
        "brand":{"options":[ "nike", "adidas","puma"]},
        "colour":{"options":["black","grey","white"]
     },
     "range":{
        "price":{"options":["0","100","1000"]
     }
  }

Select fields are checkboxes where user can select more than one option to search and Range where user selects min and max. So 2 dropdowns, one for minimum and second for maximum.

I have created checkboxes like following

<div class="form-row" v-for="(selectField, index) in selectCustomFields">
    <div class="overflow-auto options-list" v-for="(value, name) in selectField.options">
        <label class="custom-control custom-checkbox mb-3">
            <input type="checkbox" class="custom-control-input" v-model="index" :value="value" @click="onChange($event)">
            <span class="custom-control-label">
                <span class="text-dark">{{ value }}</span>
            </span>
        </label>
   </div>
</div>

How can I get the value of all checked options of termQualities?

How can I create checkbox array so that I can get all selected values?

I am trying to achieve something like this with the only difference that sidebar filters are changed depending on the product category.

Thank you

can u add a fiddle or pen for it with image of ur expected o/p? — Dcoder14

      mounted(){
        // Initialize data.selected based on your filter fields you can do this after you get customfields from server
        // For eg : if you use axios :
