Form#

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

In the controlled approach, the p-segmented-control state is externally managed using the value property and change 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 p-segmented-control 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.

The p-segmented-control lacks access to native ValidityState properties and validationMessage, and it cannot display the native validation popover. This means validation behavior and error display will need to be implemented separately if required.

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 render custom markup for label, description or message. Therefore, named slots 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.

In addition to the named slots label, description and message, there is also a label-after slot available. This slot must be used to render content after the label which is not directly part of it (e.g. an external link or a popover component).

If the p-segmented-control is in disabled/loading state and label or label-after slots are used with focusable UI elements (e.g. a or p-popover), the keyboard focus handling has to be managed manually to prevent focusing disabled elements (e.g. add tabindex="-1" on those UI elements).
