Do i have to make a new scene for this, or is it possible in first scene.
Yes, you have several options: either to switch to another scene, as you've figured out, or you could create a "window" object and display it over the scene. The windows can now contain entities therefore you can create complex designs.
Another way could be to add an extra layer to the scene. Although the layers are meant mainly for the parallax scrolling, I think you could use it for your drawer situation as well. That layer would be initially hidden and you'd only make it visible when the player opens the drawer.
