## Anatomy
The text field consists of:
- **TextField**: The root container for the text field.
- **TextField.Label**: The label that gives the user information on the text field.
- **TextField.Input**: The native HTML input of the text field, used for single line text.
- **TextField.TextArea**: The native HTML textarea of the text field, used for multiline text.
- **TextField.Description**: The description that gives the user more information on the text field.
- **TextField.ErrorMessage**: The error message that gives the user information about how to fix a validation error on the text field.
```
Copytsx
<TextField>
<TextField.Label />
<TextField.Input /> {/* or <TextField.TextArea /> */}
<TextField.Description />
<TextField.ErrorMessage />
</TextField>
```
```
Copytsx
<TextField>
<TextField.Label />
<TextField.Input /> {/* or <TextField.TextArea /> */}
<TextField.Description />
<TextField.ErrorMessage />
</TextField>
```
## Example
Favorite fruit
index.tsxstyle.css
```
Copytsx
import { TextField } from "@kobalte/core/text-field";
import "./style.css";
function App() {
return (
<TextField class="text-field">
<TextField.Label class="text-field__label">Favorite fruit</TextField.Label>
<TextField.Input class="text-field__input" />
</TextField>
);
}
```
```
Copytsx
import { TextField } from "@kobalte/core/text-field";
import "./style.css";
function App() {
return (
<TextField class="text-field">
<TextField.Label class="text-field__label">Favorite fruit</TextField.Label>
<TextField.Input class="text-field__input" />
</TextField>
);
}
```
## Usage
### Default value
An initial, uncontrolled value can be provided using the `defaultValue` prop.
Favorite fruit
```
Copytsx
<TextField defaultValue="Apple">
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
```
```
Copytsx
<TextField defaultValue="Apple">
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
```
### Controlled value
The `value` prop can be used to make the value controlled. The `onChange` event is fired when the user type into the input and receive the new value.
Favorite fruit
Your favorite fruit is: Apple.
```
Copytsx
import { createSignal } from "solid-js";
function ControlledExample() {
const [value, setValue] = createSignal("Apple");
return (
<>
<TextField value={value()} onChange={setValue}>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
<p>Your favorite fruit is: {value()}.</p>
</>
);
}
```
```
Copytsx
import { createSignal } from "solid-js";
function ControlledExample() {
const [value, setValue] = createSignal("Apple");
return (
<>
<TextField value={value()} onChange={setValue}>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
<p>Your favorite fruit is: {value()}.</p>
</>
);
}
```
### Multiline
Use the `TextField.TextArea` component instead of `TextField.Input` to create a multiline text field.
Favorite fruit
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.TextArea />
</TextField>
```
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.TextArea />
</TextField>
```
In addition, the `autoResize` prop can be used to make the textarea height adjust to it's content. Try typing in the text field below to see it in action.
Favorite fruit
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.TextArea autoResize />
</TextField>
```
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.TextArea autoResize />
</TextField>
```
### Description
The `TextField.Description` component can be used to associate additional help text with a text field.
Favorite fruit
Choose the fruit you like the most.
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
<TextField.Description>Choose the fruit you like the most.</TextField.Description>
</TextField>
```
```
Copytsx
<TextField>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
<TextField.Description>Choose the fruit you like the most.</TextField.Description>
</TextField>
```
### Error message
The `TextField.ErrorMessage` component can be used to help the user fix a validation error. It should be combined with the `validationState` prop to semantically mark the text field as invalid for assistive technologies.
By default, it will render only when the `validationState` prop is set to `invalid`, use the `forceMount` prop to always render the error message (ex: for usage with animation libraries).
Favorite fruit
Hmm, I prefer apples.
```
Copytsx
import { createSignal } from "solid-js";
function ErrorMessageExample() {
const [value, setValue] = createSignal("Orange");
return (
<TextField
value={value()}
onChange={setValue}
validationState={value() !== "Apple" ? "invalid" : "valid"}
>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
<TextField.ErrorMessage>Hmm, I prefer apples.</TextField.ErrorMessage>
</TextField>
);
}
```
```
Copytsx
import { createSignal } from "solid-js";
function ErrorMessageExample() {
const [value, setValue] = createSignal("Orange");
return (
<TextField
value={value()}
onChange={setValue}
validationState={value() !== "Apple" ? "invalid" : "valid"}
>
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
<TextField.ErrorMessage>Hmm, I prefer apples.</TextField.ErrorMessage>
</TextField>
);
}
```
### HTML forms
The text field `name` prop can be used for integration with HTML forms.
Favorite fruit
ResetSubmit
```
Copytsx
function HTMLFormExample() {
const onSubmit = (e: SubmitEvent) => {
// handle form submission.
};
return (
<form onSubmit={onSubmit}>
<TextField name="favorite-fruit">
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
<div>
<button type="reset">Reset</button>
<button type="submit">Submit</button>
</div>
</form>
);
}
```
```
Copytsx
function HTMLFormExample() {
const onSubmit = (e: SubmitEvent) => {
// handle form submission.
};
return (
<form onSubmit={onSubmit}>
<TextField name="favorite-fruit">
<TextField.Label>Favorite fruit</TextField.Label>
<TextField.Input />
</TextField>
<div>
<button type="reset">Reset</button>
<button type="submit">Submit</button>
</div>
</form>
);
}
```
