Form#

The p-textarea can be integrated into a form in two ways: controlled or uncontrolled, depending on your needs.

In the controlled approach, the textarea state is externally managed using the value property and input event to keep it in sync with your application logic. This approach is ideal for complex forms or when using a form library. Note that the component will still always update its internal value automatically when interacted with.

In the uncontrolled approach, the textarea behaves similar to a native <textarea>, automatically managing its own state and including its value in form submissions through the ElementInternals API. This is convenient for smaller forms or simple submissions.

For more details on form integration, refer to the Form section in the developing documentation for your framework of choice, or find a full form integration example in our examples repository.

Slots#

Sometimes it's useful to be able to render markup (e.g. an anchor tag) for label or message. Therefore a named slot can be used. Make sure not to define the corresponding property on the host element when a named slot is used (because a property definition is preferred over a named slot). For named slots only phrasing content is allowed.
