VSelect - Select does not work with custom 'project' slot in Vuetify 3

Question

I'm using VSelect from Vuetify 3 in my Vue 3 application and I'm trying to use item slots. But my VSelect options become unselectable

I have this VSelect element:

<v-select
    v-model="tag"
    :items="tags"
    variant="solo"
    label="Tags" >
    <template #item="{ item }" >
      <v-list>
        <v-list-item :title="item.title" />
      </v-list>
    </template>
  </v-select>

Tags and tags in data:

tag: null,
  tags: [
    { title: 'example1', value: 0 },
    { title: 'example2', value: 1 },
  ],

In the output, I selected the option with the option, but the option is not selectable:

So how to set slot "item" using selectable options for VSelect component in Vuetify 3?

Answer 1

The props object passed to the slot contains an onClick callback, which you need to bind for selection to work:

<template #item="{ item, props: { onClick } }" >
  <v-list-item :title="item.title" @click="onClick"/>
</template>

Documentation is a bit sparse at the moment, the type given is Record. In Vuetify 3.4, other values ​​are key, title, value and ref (template reference from underlying VVritualScroll) Used to update the height of the scroll bar.

When using a component with a title property (e.g. VListItem), you can bind the entire props object:

<template #item="{ props }" >
  <v-list-item v-bind="props"/>
</template>

(BTW, the #item slot has its content rendered into the v-list, no need to wrap it again)

This is a snippet:

const { createApp, ref } = Vue;
const { createVuetify } = Vuetify
const vuetify = createVuetify()
createApp({
  setup(){

    return {
       tag: ref(null),
        tags: [
          { title: 'example1', value: 0 },
          { title: 'example2', value: 1 },
        ],
    }
  }
}).use(vuetify).mount('#app')
