Did you know that in @vuejs you can add static and dynamic classes to an element at the same time?

<template>
  <ul>(
    <li v-for="item in list"
      :key="item.id"
      class="always-here"
      :class="{
        'always-here': true,
        selected: item.selected,
      }"
    >
      {{ item.name }}
    </li>
  </ul>
</template>

Great tip by @MichaelThiessen.
