My code for combining filter, sort, and search is functioning well.
<template>
<h5>List of Products</h5>
<h3>Filter</h3>
<button v-on:click="resetOptions">Reset</button>
<button v-on:click="sorting">Sorting</button>
<button v-on:click="sorting2">Sorting2</button>
<select v-model="category">
<option value="Accessories">Accessories</option>
<option value="Laptop">Laptop</option>
<option value="Stationary">Stationary</option>
</select>
<div>
<input type="checkbox" name="test" id="test" v-model="city" value='Roma' @change="uniqueCheck">
<label for="test"> Roma</label>
<input type="checkbox" name="test2" id="test2" v-model.trim="city" value='Barselona' @change="uniqueCheck">
<label for="test2"> Barselona</label>
<input type="checkbox" name="test3" id="test3" v-model.trim="city" value='Milano' @change="uniqueCheck">
<label for="test3"> Milano</label>
</div>
<input type="text" v-model="name" placeholder="Filter By Name"/>
<label for="vol">Price (between 0 and 1000):</label>
<input type="range" v-model.trim="range" min="0" max="1000" step="10"/>
<ul>
<li v-for="product in filterProducts" :key="product.name"> Product Name : {{product.name}} - Price : {{product.price}} ({{product.category}})
{{product.city}}
</li>
</ul>

I would like to implement multiple checkboxes filters. For instance, when selecting 'Barcelona' and 'Roma,' I expect the display to show products with cities 'Barcelona' and 'Roma.' The current code does not support this due to the @change function. I attempted without it but encountered issues as shown below:

Are there alternative ways to incorporate this additional filter?
