Changing the right panel gui in every choices in the left panel

Hi! So i am very new to MATLAB especially in GUIs, so what i have here is the design for my program,

So, i wanted to change the gui on the right panel every time i choose something from the left panel upon clicking 'Start Program', however it is my first time doing the gui which makes it difficult. I tried search for links, but couldn't find anything related to this. can someone help me?

In the callback function for the button, you need to put code to read the selected index in the listbox and do something with that knowledge. Something like

selectedIndex = app.listbox1.Value;
switch selectedIndex
    case 1
        % Display solid block
    case 2
        % Display hollow block
    case 3
        % Display circle       
end
