Unsolved UI expnader component

[Jehyeok]

Is there any UI component which is like 'Expander'? (refer below)
collapse and expand component http://www.wpftutorial.net/Expander.html

@Jehyeok
search in google for "qml collapsible" and you will find some examples

Sorry @raven-worx , I couldn't find right references.

Actually
I try to use 'Loader' to make similar putting Component or null in sourceComponent property.

        Loader {
            id: itemLoader
            anchors.fill: parent
            visible: !collapsed
            sourceComponent: collapsed ? null : componentItem
        }

But, I don't think it is best. Because I need to put component in it still.

    MyExpander{
        componentItem: Component{
            Rectangle{
                Text {
                }
        }
    }

It would be nice to design as other layout components to hold children in it.
Do you have any idea?

    GridLayout{
        Rectangle{
            Text {
            }
        }
    }

@raven-worx You are right. I saw them in search results, but I mean it wasn't what I want. I want to have similar like groupbox component. http://doc.qt.io/qt-5/qml-qtquick-controls-groupbox.html

You can do it like this:

Rectangle {
    implicitHeight: header.implicitHeight + (collapsed ? listview.contentHeight : 0)
    Item {} // header
    Listview {}
}

@literA2
I would like to do it like this

MyExpander{
  GridLayout{
    Rectangle{
      Text { }
      Text { }
    }
    Rectangle{
      Text { }
      Text { }
    }
  }
}

MyExpander is my new component. I would like to reuse this MyExpander object in other qml.
Under the MyExpander should be able to control its children collapsible.
