Hey everyone, I recently attempted to set up this layout:

https://i.sstatic.net/WbcBX.png

This company offers a variety of services grouped into different categories, each containing sub-options and specific details.

This is how my JSON data is structured:

    {
        "services": [{
                "name": "COVID-19",
                "options": [
                    "COVID-19 Temperature Screening System"
                ],
                "information": {
                    "images": [
                        "http://placekitten.com/300/300"
                    ],
                    "description": "Lorem ipsum dolor sit amet consectetur, adipisicing elit. Qui, in."
                }
            },
            {
                "name": "Home",
                "options": [
                    "Camera",
                    "Fire Alarm",
                    "Motion Sensor"
                ],
                "information": {
                    "images": [
                        "http://placekitten.com/300/300"
                    ],
                    "description": "Lorem ipsum dolor sit amet consectetur, adipisicing elit. Qui, in."
                }
            },
....

The main issue I'm facing is figuring out how to utilize a v-if statement alongside a v-for loop to dynamically change the displayed product based on user selection. I encountered this error message:

26:11 error The 'this.JSON' expression inside 'v-for' directive should be replaced with a computed property that returns filtered array instead. You should not mix 'v-for' with 'v-if'

Could anyone provide guidance on using a computed property for this purpose as I am uncertain about its meaning? Here's the snippet related to the services page:

<template>
  <div class="services">
    <div class="header services__header">
      <h1 :class="$mq">Services</h1>
    </div>

        <!-- GENERATE CATEGORIES -->
        <div

          v-for="(item, index) in this.JSON"
          :key="`category-${index}`"
          :class="$mq"
        >
          <input type="radio" :name="item.name" :value="item.name" v-model="currentCategory" />
          <label :for="item.name">{{item.name}}</label>

          <div v-for="(option, index) in item.options" :key="`option-${index}`" :class="$mq">
