How to loop through nested data with VueJS

Question

In my vue-app I want to loop through han array of data which contains multiple checkboxes.

filters: [
   {
    name: "Sales & marketing",
    open: false,
    items: [
        {
            employees_cvr: {
                placeholder: "employees",
                checked: false,
                click: data => {
                    ...
                }
            },
            employees_pnr: {
                placeholder: "employees_pnr",
                checked: false,
                click: data => {
                    ...
                }
            },
            date_of_origin: {
                placeholder: "Date of origin",
                checked: false,
                click: data => {
                    console.log(data);
                }
            },
            company_search: {
                placeholder: "Search for companies",
                checked: false,
                click: data => {
                    ...
                }
            }
        }
    ]
}

now, when I do a loop like this:

<div v-for="filter in filters" :key="filter.id" class="category">
    <label @click="filter.open = !filter.open">{{filter.name}}</label>
    <div class="category__rows">
       <ul v-show="filter.open">
         <li v-for="item in filter.items" :key="item.id">
           <Checkbox v-bind:data.sync="item" />
         </li>
       </ul>
   </div>
</div>

I get the name from the object, but not the items. So when I click the label to get the state open = true, the <ul> gets visible but with no data in it.

Waht am I doing wrong and can someone help me out?

You are iterating filters.items which is an array that holds one object that has multiple properties. Instead, iterate that one object.

So write this instead:

       <li v-for="item in filters.items[0]" :key="item.id">
           <Checkbox v-bind:data.sync="item" />
         </li>

This way you are actually iterating the object properties and not the array.
