VSelect - selection not working with custom "item" slot in Vuetify 3

Question

I am using VSelect from Vuetify 3 in my Vue 3 app and I am trying to use item slot. But my VSelect options become unpickable

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>

tag and tags in data:

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

in the output I have this select with options, but options are not pickable:

So how can I set a slot "item" to VSelect component in Vuetify 3 with pickable options?

The props object handed to the slot contains an onClick callback, and you need to bind it in order for selection to work:

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

The documentation is a bit sparse at the moment and gives the type as Record<string, unknown>. In Vuetify 3.4, the other values are key, title, value and ref, a template ref from the underlying VVritualScroll used to update height of the scroller.

When using a component with a title prop (like VListItem), you can just bind the whole props object:

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

(Btw. the #item slot already renders its content into a v-list, there is no need to wrap it again)

Here it is in 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')
