Form props

You can add standard form attributes such as required and disabled to the Input component:

<form
  onSubmit={(event) => {
    event.preventDefault();
  }}
>
  <Input
    placeholder="Try to submit with no text!"
    required
    sx={{ mb: 1, fontSize: 'var(--joy-fontSize-sm)' }}
  />
  <Input placeholder="It is disabled" disabled sx={{ mb: 1 }} />
  <Button type="submit">Submit</Button>
</form>

<form
  onSubmit={(event) => {
    event.preventDefault();
  }}
>
  <Input
    placeholder="Try to submit with no text!"
    required
    sx={{ mb: 1, fontSize: 'var(--joy-fontSize-sm)' }}
  />
  <Input placeholder="It is disabled" disabled sx={{ mb: 1 }} />
  <Button type="submit">Submit</Button>
</form>

Validation

Use the error prop to toggle the error state:

<Input placeholder="Type in here…" error defaultValue="Oh no, error found!" />

<Input placeholder="Type in here…" error defaultValue="Oh no, error found!" />

Decorators

The startDecorator and endDecorator props can be used to add supporting icons or elements to the input. With inputs, decorators are typically located at the top and/or bottom of the input field.

Inner HTML input

If you need to pass props to the inner HTML <input>, use slotProps={{ input: { ...props } }}. These props may include HTML attributes such as min, max, and autocomplete.

<Input
  type="number"
  defaultValue={2.5}
  slotProps={{
    input: {
      min: 1,
      max: 5,
      step: 0.1,
    },
  }}
/>

<Input
  type="number"
  defaultValue={2.5}
  slotProps={{
    input: {
      min: 1,
      max: 5,
      step: 0.1,
    },
  }}
/>

Common examples

CSS variable playground

Play around with the CSS variables available to the Avatar component to see how the design changes. You can use these to customize the component with both the sx prop and the theme.

<Input
  startDecorator={<MailIcon />}
  endDecorator={<Button>Message</Button>}
>

CSS Variables

--Input-radius

--Input-gap

--Input-placeholderOpacity

--Input-minHeight

--Input-paddingInline

--Input-decorator-childHeight

Accessibility

All inputs should have a descriptive label linked to help users understand its purpose.

The Form Control component automatically generates a unique ID that links the Input with the Form Label and Form Helper Text components:

Label

This is a helper text.

<FormControl>
  <FormLabel>Label</FormLabel>
  <Input placeholder="Placeholder" />
  <FormHelperText>This is a helper text.</FormHelperText>
</FormControl>

<FormControl>
  <FormLabel>Label</FormLabel>
  <Input placeholder="Placeholder" />
  <FormHelperText>This is a helper text.</FormHelperText>
</FormControl>

Press Enter to start editing

Alternatively, you can do this manually by targeting the input slot—see inner HTML input for details:

<label htmlFor="unique-id">Label</label>
<Input
  slotProps={{
    input: {
      id: 'unique-id',
    }
  }}
/>

Anatomy

The Input component is composed of a root <div> with an <input> nested inside:

<div class="MuiInput-root">
  <input class="MuiInput-input" />
</div>
