# Forms

**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](https://github.com/baianat/Vee-validate) and [vuelidate](https://github.com/vuelidate/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.

```markup
<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.

```markup
<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-divider></v-divider>
      <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">
        <v-card
          class="mb-12"
          color="grey lighten-1"
          height="200px"
        ></v-card>
        <v-btn
          color="primary"
          @click="e1 = 2"
        >
          Continue
        </v-btn>
        <v-btn text>Cancel</v-btn>
      </v-stepper-content>
      <v-stepper-content step="2">
        <v-card
          class="mb-12"
          color="grey lighten-1"
          height="200px"
        ></v-card>
        <v-btn
          color="primary"
          @click="e1 = 3"
        >
          Continue
        </v-btn>
        <v-btn text>Cancel</v-btn>
      </v-stepper-content>
      <v-stepper-content step="3">
        <v-card
          class="mb-12"
          color="grey lighten-1"
          height="200px"
        ></v-card>
        <v-btn
          color="primary"
          @click="e1 = 1"
        >
          Continue
        </v-btn>
        <v-btn text>Cancel</v-btn>
      </v-stepper-content>
    </v-stepper-items>
  </v-stepper>
</template>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://iron-network.gitbook.io/vuely/vuely-vuejs/ui-components/forms-elements.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
