Form Validation:

When it comes to form validation, Vuetify has a multitude of integrations and baked in functionality. Want to use a 3rd party validation plugin? Out of the box you can use Vee-validate and vuelidate.

The v-form component makes it easy to add validation to form inputs. All input components have a rules prop which takes an array of functions. These functions allow you to specify conditions in which the field is valid or invalid. Whenever the value of an input is changed, each function in the array will receive the new value. If a function returns false or a string, validation has failed.

 
<template>
  <v-form v-model="valid">
    <v-container>
      <v-row>
        <v-col
          cols="12"
          md="4"
        >
          <v-text-field
            v-model="firstname"
            :rules="nameRules"
            :counter="10"
            label="First name"
            required
          ></v-text-field>
        </v-col>
        <v-col
          cols="12"
          md="4"
        >
          <v-text-field
            v-model="lastname"
            :rules="nameRules"
            :counter="10"
            label="Last name"
            required
          ></v-text-field>
        </v-col>
        <v-col
          cols="12"
          md="4"
        >
          <v-text-field
            v-model="email"
            :rules="emailRules"
            label="E-mail"
            required
          ></v-text-field>
        </v-col>
      </v-row>
    </v-container>
  </v-form>
</template> 

Stepper:

The v-stepper component displays progress through numbered steps.

<template>
  <v-stepper v-model="e1">
    <v-stepper-header>
      <v-stepper-step :complete="e1 > 1" step="1">Name of step 1</v-stepper-step>

      <v-stepper-step :complete="e1 > 2" step="2">Name of step 2</v-stepper-step>
      <v-divider></v-divider>
      <v-stepper-step step="3">Name of step 3</v-stepper-step>
    </v-stepper-header>
    <v-stepper-items>
      <v-stepper-content step="1">
