Popup - Scrolling

This demo shows two implementations of scrolling in the Popup component.

When you click the first Show Popup button, a Popup with a native scrollbar appears. The component always displays a native scrollbar when the height of the Popup's content is greater than that of the Popup.

A click on the second Show Popup button also displays a Popup with a scrollbar, but this scrollbar belongs to the ScrollView component. This implementation is more flexible. For example, you can enable right-to-left representation or scroll the content to a specific position. For more information about the available options, refer to the ScrollView API section.

To implement the second solution, follow the steps below:

Wrap the content in the ScrollView component and place it in the Popup container.
Set the height and width of the ScrollView to 100% of the popup content area.
