# Input

> An input element to enter text.

## Usage

Use the `v-model` directive to control the value of the Input.

```vue
<template>
  <UInput model-value="" />
</template>
```

### Type

Use the `type` prop to change the input type. Defaults to `text`.

Some types have been implemented in their own components such as [Checkbox](/docs/components/checkbox), [Radio](/docs/components/radio-group), [InputNumber](/docs/components/input-number) etc. and others have been styled like `file` for example.

```vue
<template>
  <UInput type="file" />
</template>
```

> [!NOTE]
> See: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#input_types
> You can check all the available types on the MDN Web Docs.

### Placeholder

Use the `placeholder` prop to set a placeholder text.

```vue
<template>
  <UInput placeholder="Search..." />
</template>
```

### Color

Use the `color` prop to change the ring color when the Input is focused.

```vue
<template>
  <UInput color="neutral" highlight placeholder="Search..." />
</template>
```

> [!NOTE]
> The `highlight` prop is used here to show the focus state. It's used internally when a validation error occurs.

### Variant

Use the `variant` prop to change the variant of the Input.

```vue
<template>
  <UInput color="neutral" variant="subtle" :highlight="false" placeholder="Search..." />
</template>
```

### Size

Use the `size` prop to change the size of the Input.

```vue
<template>
  <UInput size="xl" placeholder="Search..." />
</template>
```

### Icon

Use the `icon` prop to show an [Icon](/docs/components/icon) inside the Input.

```vue
<template>
  <UInput icon="i-lucide-search" size="md" variant="outline" placeholder="Search..." />
</template>
```

Use the `leading` and `trailing` props to set the icon position or the `leading-icon` and `trailing-icon` props to set a different icon for each position.

```vue
<template>
  <UInput trailing-icon="i-lucide-at-sign" placeholder="Enter your email" size="md" />
</template>
```

### Avatar

Use the `avatar` prop to show an [Avatar](/docs/components/avatar) inside the Input.

```vue
<template>
  <UInput size="md" variant="outline" placeholder="Search..." />
</template>
```

### Loading

Use the `loading` prop to show a loading icon on the Input.

```vue
<template>
  <UInput loading :trailing="false" placeholder="Search..." />
</template>
```

### Loading Icon

Use the `loading-icon` prop to customize the loading icon. Defaults to `i-lucide-loader-circle`.

```vue
<template>
  <UInput loading loading-icon="i-lucide-loader" placeholder="Search..." />
</template>
```

**Nuxt:**
> [!TIP]
> See: /docs/getting-started/integrations/icons/nuxt#theme
> You can customize this icon globally in your `app.config.ts` under `ui.icons.loading` key.

**Vue:**
> [!TIP]
> See: /docs/getting-started/integrations/icons/vue#theme
> You can customize this icon globally in your `vite.config.ts` under `ui.icons.loading` key.

### Disabled

Use the `disabled` prop to disable the Input.

```vue
<template>
  <UInput disabled placeholder="Search..." />
</template>
```

## Examples

### With clear button

You can put a [Button](/docs/components/button) inside the `#trailing` slot to clear the Input.

```vue [InputClearButtonExample.vue]
<script setup lang="ts">
const value = ref('Click to clear')
</script>

<template>
  <UInput
    v-model="value"
    placeholder="Type something..."
    :ui="{ trailing: 'pe-1' }"
  >
    <template v-if="value?.length" #trailing>
      <UButton
        color="neutral"
        variant="link"
        size="sm"
        icon="i-lucide-circle-x"
        aria-label="Clear input"
        @click="value = ''"
      />
    </template>
  </UInput>
</template>
```

### With copy button

You can put a [Button](/docs/components/button) inside the `#trailing` slot to copy the value to the clipboard.

```vue [InputCopyButtonExample.vue]
<script setup lang="ts">
import { useClipboard } from '@vueuse/core'

const value = ref('npx nuxt module add ui')

const { copy, copied } = useClipboard()
</script>

<template>
  <UInput
    v-model="value"
    :ui="{ trailing: 'pr-0.5' }"
  >
    <template v-if="value?.length" #trailing>
      <UTooltip text="Copy to clipboard" :content="{ side: 'right' }">
        <UButton
          :color="copied ? 'success' : 'neutral'"
          variant="link"
          size="sm"
          :icon="copied ? 'i-lucide-copy-check' : 'i-lucide-copy'"
          aria-label="Copy to clipboard"
          @click="copy(value)"
        />
      </UTooltip>
    </template>
  </UInput>
</template>
```

### With password toggle

You can put a [Button](/docs/components/button) inside the `#trailing` slot to toggle the password visibility.

```vue [InputPasswordToggleExample.vue]
<script setup lang="ts">
const show = ref(false)
const password = ref('')
</script>

<template>
  <UInput
    v-model="password"
    placeholder="Password"
    :type="show ? 'text' : 'password'"
    :ui="{ trailing: 'pe-1' }"
  >
    <template #trailing>
      <UButton
        color="neutral"
        variant="link"
        size="sm"
        :icon="show ? 'i-lucide-eye-off' : 'i-lucide-eye'"
        :aria-label="show ? 'Hide password' : 'Show password'"
        :aria-pressed="show"
        aria-controls="password"
        @click="show = !show"
      />
    </template>
  </UInput>
</template>

<style>
/* Hide the password reveal button in Edge */
::-ms-reveal {
    display: none;
}
</style>
```

### With password strength indicator

You can use the [Progress](/docs/components/progress) component to display the password strength indicator.

```vue [InputPasswordStrengthIndicatorExample.vue]
<script setup lang="ts">
const show = ref(false)
const password = ref('')

function checkStrength(str: string) {
  const requirements = [
    { regex: /.{8,}/, text: 'At least 8 characters' },
    { regex: /\d/, text: 'At least 1 number' },
    { regex: /[a-z]/, text: 'At least 1 lowercase letter' },
    { regex: /[A-Z]/, text: 'At least 1 uppercase letter' }
  ]

  return requirements.map(req => ({ met: req.regex.test(str), text: req.text }))
}

const strength = computed(() => checkStrength(password.value))
const score = computed(() => strength.value.filter(req => req.met).length)

const color = computed(() => {
  if (score.value === 0) return 'neutral'
  if (score.value <= 1) return 'error'
  if (score.value <= 2) return 'warning'
  if (score.value === 3) return 'warning'
  return 'success'
})

const text = computed(() => {
  if (score.value === 0) return 'Enter a password'
  if (score.value <= 2) return 'Weak password'
  if (score.value === 3) return 'Medium password'
  return 'Strong password'
})
</script>

<template>
  <div class="space-y-2">
    <UFormField label="Password">
      <UInput
        v-model="password"
        placeholder="Password"
        :color="color"
        :type="show ? 'text' : 'password'"
        :aria-invalid="score < 4"
        aria-describedby="password-strength"
        :ui="{ trailing: 'pe-1' }"
        class="w-full"
      >
        <template #trailing>
          <UButton
            color="neutral"
            variant="link"
            size="sm"
            :icon="show ? 'i-lucide-eye-off' : 'i-lucide-eye'"
            :aria-label="show ? 'Hide password' : 'Show password'"
            :aria-pressed="show"
            aria-controls="password"
            @click="show = !show"
          />
        </template>
      </UInput>
    </UFormField>

    <UProgress
      :color="color"
      :indicator="text"
      :model-value="score"
      :max="4"
      size="sm"
    />

    <p id="password-strength" class="text-sm font-medium">
      {{ text }}. Must contain:
    </p>

    <ul class="space-y-1" aria-label="Password requirements">
      <li
        v-for="(req, index) in strength"
        :key="index"
        class="flex items-center gap-0.5"
        :class="req.met ? 'text-success' : 'text-muted'"
      >
        <UIcon :name="req.met ? 'i-lucide-circle-check' : 'i-lucide-circle-x'" class="size-4 shrink-0" />

        <span class="text-xs font-light">
          {{ req.text }}
          <span class="sr-only">
            {{ req.met ? ' - Requirement met' : ' - Requirement not met' }}
          </span>
        </span>
      </li>
    </ul>
  </div>
</template>
```

### With character limit

You can use the `#trailing` slot to add a character limit to the Input.

```vue [InputCharacterLimitExample.vue]
<script setup lang="ts">
const value = ref('')
const maxLength = 15
</script>

<template>
  <UInput
    v-model="value"
    :maxlength="maxLength"
    aria-describedby="character-count"
    :ui="{ trailing: 'pointer-events-none' }"
  >
    <template #trailing>
      <div
        id="character-count"
        class="text-xs text-muted tabular-nums"
        aria-live="polite"
        role="status"
      >
        {{ value?.length }}/{{ maxLength }}
      </div>
    </template>
  </UInput>
</template>
```

### With keyboard shortcut

You can use the [Kbd](/docs/components/kbd) component inside the `#trailing` slot to add a keyboard shortcut to the Input.

```vue [InputKbdExample.vue]
<script setup lang="ts">
const input = useTemplateRef('input')

defineShortcuts({
  '/': () => {
    input.value?.inputRef?.focus()
  }
})
</script>

<template>
  <UInput
    ref="input"
    icon="i-lucide-search"
    placeholder="Search..."
  >
    <template #trailing>
      <UKbd value="/" />
    </template>
  </UInput>
</template>
```

> [!NOTE]
> See: /composables/define-shortcuts
> This example uses the `defineShortcuts` composable to focus the Input when the  key is pressed.

### With mask

There's no built-in support for masks, but you can use libraries like [maska](https://github.com/beholdr/maska) to mask the Input.

```vue [InputMaskExample.vue]
<script setup lang="ts">
import { vMaska } from 'maska/vue'
</script>

<template>
  <div class="flex flex-col gap-2">
    <UInput v-maska="'#### #### #### ####'" placeholder="4242 4242 4242 4242" icon="i-lucide-credit-card" />

    <div class="flex items-center gap-2">
      <UInput v-maska="'##/##'" placeholder="MM/YY" icon="i-lucide-calendar" />
      <UInput v-maska="'###'" placeholder="CVC" />
    </div>
  </div>
</template>
```

### With floating label

You can use the `#default` slot to add a floating label to the Input.

```vue [InputFloatingLabelExample.vue]
<script setup lang="ts">
const value = ref('')
</script>

<template>
  <UInput v-model="value" placeholder="" :ui="{ base: 'peer' }">
    <label class="pointer-events-none absolute left-0 -top-2.5 text-highlighted text-xs font-medium px-1.5 transition-all peer-focus:-top-2.5 peer-focus:text-highlighted peer-focus:text-xs peer-focus:font-medium peer-placeholder-shown:text-sm peer-placeholder-shown:text-dimmed peer-placeholder-shown:top-1.5 peer-placeholder-shown:font-normal">
      <span class="inline-flex bg-default px-1">Email address</span>
    </label>
  </UInput>
</template>
```

### Within a FormField

You can use the Input within a [FormField](/docs/components/form-field) component to display a label, help text, required indicator, etc.

```vue [InputFormFieldExample.vue]
<script setup lang="ts">
const email = ref('')
</script>

<template>
  <UFormField label="Email" help="We won't share your email." required>
    <UInput v-model="email" placeholder="Enter your email" icon="i-lucide-at-sign" />
  </UFormField>
</template>
```

> [!TIP]
> See: /docs/components/form
> It also provides validation and error handling when used within a Form component.

### Within a FieldGroup

You can use the Input within a [FieldGroup](/components/field-group) component to group multiple elements together.

```vue [InputFieldGroupExample.vue]
<script setup lang="ts">
const value = ref('')
const domains = ['.com', '.dev', '.org']
const domain = ref(domains[0])
</script>

<template>
  <UFieldGroup>
    <UInput
      v-model="value"
      placeholder="nuxt"
      :ui="{
        base: 'pl-14.5',
        leading: 'pointer-events-none'
      }"
    >
      <template #leading>
        <p class="text-sm text-muted">
          https://
        </p>
      </template>
    </UInput>

    <USelectMenu v-model="domain" :items="domains" />
  </UFieldGroup>
</template>
```
