Usage
Design Guidelines
See Figma: Warp - Components / Text Area
Accessibility
If a visible label isn't specified, an aria-label
must be provided to the text area for accessibility. If the field is labeled by a separate element, an aria-labelledby
prop must be provided using the id of the labeling element instead.

Import

import { TextArea } from '@warp-ds/react';
or import it individually to optimize your JS bundle size by adding only the components you need:
import { TextArea } from '@warp-ds/react/components/textarea';

Value
A TextArea's value is empty by default, but an initial, uncontrolled, value can be provided using the defaultValue
prop. Alternatively, a controlled value can be provided using the value
prop.
function Example() {
let [value, setValue] = React.useState('Lorem ipsum');
return (
<div className="flex space-x-32">
<TextArea label="Description (Uncontrolled)" defaultValue="Lorem ipsum" />
<TextArea
label="Description (Controlled)"
onChange={(event) => setValue(event.target.value)}
value={value}
/>
</div>
);
}
Labeling
A visual label should be provided for the TextArea using the label
prop.
Optional
Add the optional
prop to indicate that the textarea is not required.
<TextArea label="Description" optional />
Help text
TextAreas can provide additional context with helpText
if the label and placeholder aren't enough.
<TextArea label="Description" helpText="Maximum 200 characters" />
Validation
TextAreas can communicate to the user whether the current value is invalid. Implement your own validation logic in your app and set the invalid
prop to display it as invalid.
invalid
is often paired with helpText
to provide feedback to the user about the error.
<TextArea label="Description" invalid helpText="Maximum 200 characters" />
Visual options
Placeholder
<TextArea label="Description" placeholder="Lorem ipsum dolor sit amet" />
Placeholder text can be used to describe the expected value or formatting for the TextArea. Placeholder text will only appear when the TextArea is empty, and should not be used as a substitute for labeling the component with a visible label.
Disabled
Keep in mind that using disabled in its current form is an anti-pattern. There will always be users who don't understand why an element is disabled, or users who can't even see that it is disabled because of poor lighting conditions or other reasons. Please consider more informative alternatives before choosing to use disabled on an element.
<div className="flex flex-col y-space-32">
<TextArea label="Description" disabled value="Lorem ipsum dolor sit amet" />
<TextArea label="Description" disabled />
</div>
Read only
The readOnly
boolean prop makes the TextArea's text content immutable. Unlike disabled
the TextArea remains focusable and the contents can still be copied. See the MDN docs for more information.
<div className="flex flex-col y-space-32">
<TextArea
label="Description"
readOnly
defaultValue="Lorem ipsum dolor sit amet"
/>
<TextArea label="Description" readOnly />
</div>
Height (text rows)
The minimumRows prop sets the minimum number of text rows the TextArea should show.
<TextArea label="Description" minimumRows={3} />
The maximumRows
prop sets the maximum number of text rows the TextArea should show.
<TextArea
label="Description"
maximumRows={3}
defaultValue={'Lorem\nipsum\ndolor\nsit\namet'}
/>
