I'm using last version of vuetify and trying to figure out how to make slots work. Documentation about select may be find here

VSelectWithValidation

<v-select v-model="innerValue" :error-messages="errors" v-bind="$attrs" v-on="$listeners">
  <template slot="selection" slot-scope="data">
      {{ data.item.name }}
  </template>
   <template slot="item" slot-scope="data">
      {{ data.item.name }} - {{ data.item.description }}
  </template>
</v-select>

TestComponent

<VSelectWithValidation
    rules="required"
    :items="items"
    v-model="select"
    label="Select">
    // I WOULD LIKE SLOTS TO BE AT THIS LEVEL
</VSelectWithValidation>

Basically, I would like the slots to be customized so I need to move them out of the VSelectWithValidation component to be set on the TestComponent

I tried different variations with no success.

VSelectWithValidation

You need to create slot inside your template slot item and bind scope data to able to use from other component ..

<template slot="item" slot-scope="data">
   <slot name="item" v-bind="data"></slot>
</template>

TestComponent

You can access that slot by writing v-slot:YourSlotName="hereIsBindData"

<template v-slot:item="data">
    {{ data.item.name }} // you can code here whatever you like
</template>
