Time Custom Input Component

By Geoff Ball

A custom input component that lets users enter a time without requiring a date.

Your input component file (e.g., time-input.js)

import React from 'react';
import FormField from 'part:@sanity/components/formfields/default'
import {PatchEvent, set} from 'part:@sanity/form-builder/patch-event'
import {TextInput} from '@sanity/ui'

export const TimeInput = React.forwardRef((props, ref) => {
  const { type, onChange, value } = props;
  const { title, description } = type;
  return (
    <FormField label={title} description={description}>
        onChange={event => {onChange(PatchEvent.from(set(event.target.value)))}}

Your schema file

import { TimeInput } from '../path/to/time-input';

export default {
  name: "documentName",
  title: "Document Name",
  type: "document",
  fields: [

    // ...,

      name: 'time',
      title: 'Time',
      type: 'string',
      description: 'Please enter a time.',
      inputComponent: TimeInput,

    // ...


The Datetime schema type built into Sanity is useful, but sometimes you only want to work with times. Using a custom input component, we can add an HTML input with type="time", which will not require a date and stores the value consistently (as a string in 24-hour format).

The description property is optional.

The name and file location of your input component do not matter—you just need to be able to import the file into your schema.

  1. Create a file for your input component (I used time-input.js and put it in a components/ directory in the root of my studio).
  2. Add the input component code into time-input.js.
  3. In your schema file, do a named import of TimeInput:

    import { TimeInput } from '../path/to/time-input';
  4. In that same schema file, add an object with a type of string and an inputComponent property of TimeInput.
