Text fields

Usage

Text fields function similarly to <input> elements, serving as containers with labels to facilitate user input.

Label

<TextField label="Label" value="Value" />
<TextField label="Label" value="Value" variant="outlined" />

Input type

The type attribute of a text field changes how the text field works, such as displaying a different keyboard or providing default validation.

type="text" (default)
type="email"
type="password"
type="url"
type="number"
type="search"
type="tel"
type="textarea"

Password

<TextField label="Email" type="email" variant="outlined" />
<TextField label="Password" type="password" variant="outlined" />

Disabled

Label

<TextField label="Label" disabled value="Value" />
<TextField label="Label" disabled value="Value" variant="outlined" />

Labels

Country

City

<TextField label="Country" variant="outlined" />
<TextField placeholder="email@domain.com" variant="outlined" />
<label id="city-label">
	City
	<TextField variant="outlined" aria-labelledby="city-label" />
</label>

bookmark Nesting text fields in labels without aria-labelledby is not currently supported. If you want to avoid using an id, you can use aria-label instead.

<TextField label="Resize" type="textarea" />
<TextField label="Resize" type="textarea" variant="outlined" />

		<IconButton toggle title="Toggle visibility">
