The component is a special layout component and you can only place card components on it.

Only the header is visible on collapsed cards, the card contents remain invisible. If the user clicks on a collapsed card’s header, it expands, and if it was expanded, it collapses.

    • afterDraw

      public void afterDraw()
      Description copied from class: Component
      The operations to be executed after the drawing of the component

      By default, this is an empty method. It has to be overwritten on a component or page if additional operations have to be executed after the drawing process. One such operation is data retrieval, which shouldn't run in constructors so that the user could see results of an operation or navigation process.

      Overrides:
      afterDraw in class Component<CardAccordion>

    • writeHTML

      public boolean writeHTML(StringWriter writer)
      Description copied from class: Component
      Creates the component's HTML equivalent

      This method doesn't need to be used during application development. This method is used when developing a custom component. When creating a custom component, this method needs to be implemented. In the parameter (StringWriter class) the component's HTML equivalent must be specified, and the method has to return with a Boolean value. This boolean value determines if the component was drawn. If the user doesn't have access right to the component, or if the component couldn't be drawn, it should return with false. Otherwise, it must return with true.

      Specified by:
      writeHTML in class Component<CardAccordion>
      Returns:
      If the componentwas drawn, true, otherwise false
