Customizing item-text in v-select

Yes you can, using scoped slot as described in the doc and provide a template.

For v-select you have two scoped slot :

• selection : to describe how v-select should render items when selected
• item : to describe how v-select should render items when opened

It looks like this :

<v-select> // Don't forget your props
  <template slot="selection" slot-scope="data">
    <!-- HTML that describe how select should render selected items -->
    {{ data.item.name }} - {{ data.item.description }}
  </template>
  <template slot="item" slot-scope="data">
    <!-- HTML that describe how select should render items when the select is open -->
    {{ data.item.name }} - {{ data.item.description }}
  </template>
</v-select>

Vuetify Doc about Scoped Slot in V-Select

---

Edit for Vuetify 1.1.0+ : Those slots are also available with new components v-autocomplete and v-combobox as they inherit from v-select.

---

Edit for Vue 2.6+, replace :

• slot="selection" slot-scope="data" by v-slot:selection="data"
• slot="item" slot-scope="data" by v-slot:item="data"

Slot removes autoselect on focus.

item-text tye can be: string | array | function

then we can make:

:item-text="text"

and

methods: {
  text: item => item.name + ' — ' + item.description
}

Shorthand :

:item-text="item => item.name +' - '+ item.description"

Here's an example in simple following code:

<template>
  <v-select
    label="Names"
    v-model="name"
    :items="names"
    item-value="id"
    item-text="name"
    return-object
  >
    <template v-slot:selection="{ item }">
      {{ getText(item) }}
    </template>
    <template v-slot:item="{ item }">
      {{ getText(item) }}
    </template>
  </v-select>
</template>

<script> 
export default {
  data: () => ({
    names: [
      { id: 1, name: 'Paul', age: 23 },
      { id: 2, name: 'Marcelo', age: 15 },
      { id: 3, name: 'Any', age: 30 },
    ],
    name: null,
  }),
  methods: {
    getText(item) => `${item.name} - ${item.text}`,
  },
}   
</script>
