Changing Custom Property on hover || VUEJS

Trying to become friends with VUEJS. Got stuck on some simple stuff, couldn't google it. So I'm using MuseUi framework in my App. Well I want to do a simple thing, change the value of the property for each specific element on hover 

 <mu-paper :zDepth="1" v-on:mouseover=" ???? " class="searchBox">

I need to change:zDepth to 3 for example, on hover of the element. How could I achieve that?

full code snippet 

<template>
<div>
    <div class="column is-one-quarter">
        <mu-paper :zDepth="paperHover" v-on:mouseover="changePaper" class="searchBox">
            <mu-text-field fullWidth="true" :hintText="searchHint" v-model="query" class="demo-radio"/><br/>
                <mu-radio label="Name" name="group" nativeValue="1" v-model="selected" class="demo-radio"/>
                <mu-radio label="Manager" name="group" nativeValue="2" v-model="selected" class="demo-radio"/>
                <mu-radio label="Department" name="group" nativeValue="3" v-model="selected" class="demo-radio"/>
                <mu-radio label="Stage" name="group" nativeValue="4" v-model="selected" class="demo-radio"/>
                <mu-radio label="Deadline" name="group" nativeValue="5" v-model="selected" class="demo-radio"/>
                <mu-radio label="Start Date" name="group" nativeValue="6" v-model="selected" class="demo-radio"/>
        </mu-paper>
    </div>

The easiest way is probably to wrap the mu-paper component in another component where you can encapsulate the hover behavior.

// MuPaperHover.vue

<template>
  <mu-paper :z-depth="zDepth" @mouseenter.native="zDepth = 3" @mouseleave.native="zDepth = 1">
    <slot/>
  </mu-paper>
</template>

<script>
  export default {
    data() {
      return {
        zDepth: 1,
      };
    },
  };
</script>

You can then use mu-paper-hover in place of mu-paper.

I'm not familiar with MuseUI. However, I've written a Vue.js training course. In Vue, the area where your "????" are, should be a JavaScript expression. A typical practice is to call a method on your Vue instance that would then update the value of the property for the specific element. Without more details, it's hard to provide specifics.

The bottom line is, the "????" can be a JavaScript expression.
