I'm struggling here applying conditions on the breakpoints in Vue/Vuetify
Basically, I want to say... if the length of the array is divisible by 2, then MD=6, if it is divisible by 3 then MD=12
<v-col cols="12"
:md="module.plannings.length % 2 === 0 ? 6 ? module.plannings.length % 2 === 0 ? 12 : 12"
v-for="planning in module.plannings"
:key="planning.id"
>
Clearly I'm going about it the wrong way here.. what would be the correct syntax?
You can make computed property:
new Vue({
el: '#app',
vuetify: new Vuetify(),
data() {
return {
module: {id: 0, plannings: [0,1,2,3,4,5]}
}
},
computed: {
msize() {
return this.module.plannings.length % 2 === 0 ?
6 : this.module.plannings.length % 3 === 0 ?
12 : 12
}
}

<script src="https://cdn.jsdelivr.net/npm/vuetify@2.x/dist/vuetify.js"></script>Correct syntax will be :md="plannings.length % 2 === 0 ? 6 : 12"
Demo :
new Vue({

vuetify: new Vuetify(),
data: () => ({
plannings: [{
id: 1

id: 2
}]
}),

<div id="app">

<v-col

v-for="planning in plannings"

{{ planning.id }}
