Textarea

<sl-textarea> | SlTextarea
Since 1.0 stable

Textareas collect data from the user and allow multiple lines of text.

<sl-textarea></sl-textarea>

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>

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>

Rows

Use the rows attribute to change the number of text rows that get shown.

<sl-textarea rows="2"></sl-textarea>

Placeholders

Use the placeholder attribute to add a placeholder.

<sl-textarea placeholder="Type something"></sl-textarea>

Filled Textareas

Add the filled attribute to draw a filled textarea.

<sl-textarea placeholder="Type something" filled></sl-textarea>

Disabled

Use the disabled attribute to disable a textarea.

<sl-textarea placeholder="Textarea" disabled></sl-textarea>

Sizes

Use the size attribute to change a textarea’s size.

<sl-textarea placeholder="Medium" size="medium"></sl-textarea>

Prevent Resizing

By default, textareas can be resized vertically by the user. To prevent resizing, set the resize attribute to none.

Expand with Content

Textareas will automatically resize to expand to fit their content when resize is set to auto.
