So I have the following HTML on my Vue page
<div v-for="profile in lab.profiles" v-if="edit || profile.active" class="lab-tests-row-div" @mouseover="">
<div class="clickBox" :class="['clickBox-' + lab.id + '-' + profile.id]" @click="openInfoPopup"></div>
<p class="lab-tests-row test-info-row" v-bind:class="{'active': profile.active}">
<span v-bind:class="{'opacity50':!profile.active}">{{profile.name}}</span>
<i v-if="edit" class="fa fa-minus pull-right removeTestIcon" aria-hidden="true" @click="toggleProfile(lab.id, profile.id)"></i>
<span class="pull-right" v-bind:class="{'opacity50':!profile.active}">{{profile.code}}</span>
</p>
</div>
I want to show the element 'clickBox' when the user hovers over that row, if I use a v-if with a boolean and change it on mouseover they will all show since they are in a v-for, how I only show the div in the row they are hovering over?
In the v-for directive you can get the index of the element v-for="(profile, index)
Use that index to only show the style you want it, in your template.
for example.
new Vue({
el: '#app',
data: {
selected : 0
}
})
.selectedClass {
background: lightblue
}
.hoverClass:hover {
background: lightcoral
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<main id="app">
<div v-for="(elem, index) in 4">
<p class="hoverClass" :class="{'selectedClass': selected === index}" @click="selected = index" >{{elem}}</p>
</div>
</main>

Edited
It's perfeclty fine combine class="..."
with the Vue binding :class="..."

For nested v-for
declare another name for index.
new Vue({
el: '#app'
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<main id="app">
<div v-for="(item, i) in 2">
<div v-for="(elem, j) in 3">
v-for item {{ i }} v-for elem {{ j }}
</div>
</div>
</main>
