React Form Text Component

React textarea components. Give textual form `<textarea>`s an upgrade with custom styles, sizing, focus states, validation, and more.

Other frameworks

CoreUI components are available as native Angular, Bootstrap (Vanilla JS), and Vue components. To learn more please visit the following pages.

Example#

<CForm>
  <CFormTextarea
    id="exampleFormControlTextarea1"
    label="Example textarea"
    rows={3}
    text="Must be 8-20 words long."
  ></CFormTextarea>
</CForm>

If you need to add custom classNames to form's components, or need to add some custom elements you can add each form component separately. Please check the example below.

<CFormLabel htmlFor="exampleFormControlTextarea1">Example textarea</CFormLabel>
<CFormTextarea id="exampleFormControlTextarea1" rows={3}></CFormTextarea>
<CFormText component="span" id="passwordHelpInline">Must be 8-20 words long.</CFormText>

Disabled#

Add the disabled boolean attribute on an textarea to give it a grayed out appearance and remove pointer events.

<CFormTextarea
  className="mb-3"
  placeholder="Disabled textarea"
  aria-label="Disabled textarea example"
  disabled
></CFormTextarea>

Readonly#

Add the readOnly boolean attribute on an textarea to prevent modification of the textarea's value. Read-only textareas appear lighter (just like disabled textareas), but retain the standard cursor.

<CFormTextarea
  placeholder="Readonly textarea"
  aria-label="Readonly textarea example"
  disabled
  readOnly
></CFormTextarea>
