How to draw shape and make slide event?

[Munkhtamir]

Hello guys. I am a bit confused about drawing the following shape using Rectangle?

When I click green buttons, a following blue menu should appear.

Thank you,

I have no idea about the sliding part, your question is vague to say the least, but here is how I would create the 'l-shape' rectangle.

I have deliberately left the lower part of the shape another shade of blue so you can see how it is 'joined'.

import QtQuick 2.1    
import QtQuick.Window 2.12
   
Window {

    visible: true
    width: 640
    height: 540

    Rectangle {    
        id: panel    
        x: 10; y: 10    
        width: 300    
        height: 500    
        color: "lightblue"    
    }    
    Rectangle {    
        id: panelPart    
        x: 10; y: 10    
        anchors.left: parent.left +5    
        anchors.bottom: panel.bottom    
        height: 100; width: 400    
        color: "darkblue"    
    }    
}

I think, what you're looking for is a Drawer

Thank you for help guys. I have solved my problem using Canvas. @J-Hilk was also good idea.
