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 similarly 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#

Use named slots when label, description or message need markup such as a link. Do not set the corresponding host property at the same time, because properties take precedence. Named slots only accept phrasing content.

Alongside label, description and message, you can also use label-after for content that should appear after the label but is not part of the label itself, such as an external link or popover.

In disabled/loading state, slotted focusable UI elements (e.g. a) will still receive keyboard focus. Add tabindex="-1" to those UI elements.

The label-after slot is not affected by a disabled/loading state at all.
