Examples

Pattern

Use the pattern prop to define a custom pattern for the OTP input.

<script lang="ts">
  import * as InputOTP from "$lib/components/ui/input-otp/index.js";
  import { REGEXP_ONLY_DIGITS_AND_CHARS } from "bits-ui";
</script>
 
<InputOTP.Root maxlength={6} pattern={REGEXP_ONLY_DIGITS_AND_CHARS}>
  {#snippet children({ cells })}
    <InputOTP.Group>
      {#each cells as cell (cell)}
        <InputOTP.Slot {cell} />
      {/each}
    </InputOTP.Group>
  {/snippet}
</InputOTP.Root>

<script lang="ts">
  import * as InputOTP from "$lib/components/ui/input-otp/index.js";
  import { REGEXP_ONLY_DIGITS_AND_CHARS } from "bits-ui";
</script>
 
<InputOTP.Root maxlength={6} pattern={REGEXP_ONLY_DIGITS_AND_CHARS}>
  <!-- ... -->
</InputOTP.Root>

Separator

You can use the InputOTP.Separator component to add a separator between the groups of cells.

<script lang="ts">
  import * as InputOTP from "$lib/components/ui/input-otp/index.js";
</script>
 
<InputOTP.Root maxlength={6}>
  {#snippet children({ cells })}
    <InputOTP.Group>
      {#each cells.slice(0, 2) as cell (cell)}
        <InputOTP.Slot {cell} />
      {/each}
    </InputOTP.Group>
    <InputOTP.Separator />
    <InputOTP.Group>
      {#each cells.slice(2, 4) as cell (cell)}
        <InputOTP.Slot {cell} />
      {/each}
    </InputOTP.Group>
    <InputOTP.Separator />
    <InputOTP.Group>
      {#each cells.slice(4, 6) as cell (cell)}
        <InputOTP.Slot {cell} />
      {/each}
    </InputOTP.Group>
  {/snippet}
</InputOTP.Root>

<script lang="ts">
  import * as InputOTP from "$lib/components/ui/input-otp/index.js";
</script>
 
<InputOTP.Root maxlength={4}>
  {#snippet children({ cells })}
    <InputOTP.Group>
      {#each cells.slice(0, 2) as cell}
        <InputOTP.Slot {cell} />
      {/each}
    </InputOTP.Group>
    <InputOTP.Separator />
    <InputOTP.Group>
      {#each cells.slice(2, 4) as cell}
