Textarea
<sl-textarea> | SlTextarea
Textareas collect data from the user and allow multiple lines of text.
<sl-textarea></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea />;
This component works with standard <form> elements. Please refer to the section on
form controls to learn more about form submission and
client-side validation.
Examples
Labels
Use the label attribute to give the textarea an accessible label. For labels that contain HTML,
use the label slot instead.
<sl-textarea label="Comments"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea label="Comments" />;
Help Text
Add descriptive help text to a textarea with the help-text attribute. For help texts that
contain HTML, use the help-text slot instead.
<sl-textarea label="Feedback" help-text="Please tell us what you think."> </sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea label="Feedback" help-text="Please tell us what you think." />;
Rows
Use the rows attribute to change the number of text rows that get shown.
<sl-textarea rows="2"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea rows={2} />;
Placeholders
Use the placeholder attribute to add a placeholder.
<sl-textarea placeholder="Type something"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea placeholder="Type something" />;
Filled Textareas
Add the filled attribute to draw a filled textarea.
<sl-textarea placeholder="Type something" filled></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea placeholder="Type something" filled />;
Disabled
Use the disabled attribute to disable a textarea.
<sl-textarea placeholder="Textarea" disabled></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea placeholder="Textarea" disabled />;
Sizes
Use the size attribute to change a textarea’s size.
<sl-textarea placeholder="Small" size="small"></sl-textarea> <br /> <sl-textarea placeholder="Medium" size="medium"></sl-textarea> <br /> <sl-textarea placeholder="Large" size="large"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => ( <> <SlTextarea placeholder="Small" size="small"></SlTextarea> <br /> <SlTextarea placeholder="Medium" size="medium"></SlTextarea> <br /> <SlTextarea placeholder="Large" size="large"></SlTextarea> </> );
Prevent Resizing
By default, textareas can be resized vertically by the user. To prevent resizing, set the
resize attribute to none.
<sl-textarea resize="none"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea resize="none" />;
Expand with Content
Textareas will automatically resize to expand to fit their content when resize is set to
auto.
<sl-textarea resize="auto"></sl-textarea>
import SlTextarea from '@shoelace-style/shoelace/dist/react/textarea'; const App = () => <SlTextarea resize="auto" />;
