class: TitledPane

[130:7] extends: Node, Control, Labeled

The TitledPane class wraps the JavaFX TitledPane control, a collapsible panel that displays a title bar and an optional content area beneath it. Clicking the title bar expands or collapses the content, and this transition can be animated. TitledPane extends Labeled, so the title bar text, font, and graphic are all styled through the Labeled CSS properties. Two additional CSS properties control whether the expand/collapse animation plays and whether the pane can be collapsed at all.
