Collapsible Element Properties: collapsible & collapsed

This code snippet includes two properties for a collapsible element: "collapsible" and "collapsed".\n\nThe "collapsible" property is set to "true", which means that the element can be collapsed or expanded by the user.\n\nThe "collapsed" property is set to "true", which means that the element is initially in a collapsed state. The user can expand it if desired.\n\nThese properties are often used in conjunction with UI components like accordions or collapsible panels to provide a way for users to hide or show content as needed.
