In my form, I have a checkbox and I want to be able to use v-if directly to display or hide sections based on the selected checkbox values.
Can this be done using v-if, or do I need to use watch:?

Yes, it is definitely possible to achieve that. One suggestion would be to incorporate a data model tied to the checkbox that can switch between true and false values. This will enable you to control the visibility of content using v-if.
For instance:
<template>
<input type="checkbox" v-model="showContent" value="triggerString" />
<p v-if="showContent === 'triggerString'">Lorem ipsum</p>
</template>
<script>
export default {
data() {
return {
showContent: false
}
}
}
</script>
In general, it's advisable to avoid using watch unnecessarily.
Update: Based on the provided JSFiddle, here's how you can implement it solely with v-if
<template>
<input type="checkbox"
v-model="section"
name="section"
value="Epiphone"
id="epiphone">
<label for="epiphone">Epiphone</label>
<section v-if="section.includes('Epiphone')">
<h1>Epiphone</h1>
</section>
</template>
<script>
export default {
data() {
return {
section: []
}
}
}
</script>
As there is bidirectional binding happening with the section array, an extra div object is not required since all tracking occurs within the section object.
Remember that v-if supports JavaScript expressions, allowing you to integrate logic directly into it instead of relying on a separate watch method.
I hope this clarifies your query!
