<p>Currently I have a v-tab that has four tabs with image icons and text. However, when the tab is active, the active tab icon should change to another image. what should I do? </p> <pre class="brush:php;toolbar:false;"><v-tabs v-model="tabs" class="tabs-menu"> <v-tab v-for="item in items" :key="item.id" > <img :src="item.icon" /> {{ item.name }} </v-tab> </v-tabs> data() { return { tabs: null, items: [ { icon: "/planeInactive.svg", name: "plane" }, { icon: "/hotelInactive.svg", name: "hotel" }, { icon: "/planehotelInactive.svg", name: "plane hotel" }, { icon: "/planeInactive.svg", name: "students" }, ], }; },</pre></p>

    1. Use some default values ​​for your v-model and 'tab' make the tab active by default. (I'm using the tab's name attribute in v-model, but you can use any unique attribute you want. )
    2. Use this v-model to check which tab is active and update the icon using conditional operators. (I used dummy icons, you can use yours. )

    In this demo, you should see that when the tab is active, a colored flight icon will be displayed, otherwise a black flight icon will be displayed.
