Scrollbar and buttons

Hi, I’m trying to put scrollbar next to the buttons. But I can’t do it. Please can anyone help me?

My code:

function OnGUI () {
    if (vyber){
        form = false;
    
        if (GUI.Button (Rect (50,50,Screen.width - 100,100), "Mamka")){
    
        }
        if (GUI.Button (Rect (50,150,Screen.width - 100,100), "Miláček")){
    
        }
        if (GUI.Button (Rect (50,250,Screen.width - 100,100), "Brácha")){
    
        }
        if (GUI.Button (Rect (50,350,Screen.width - 100,100), "Děda")){
        
        }
        if (GUI.Button (Rect (50,450,Screen.width - 100,100), "Tatka")){
    
        }
        if (GUI.Button (Rect (50,550,Screen.width - 100,100), "Teta")){
    
        }
        if (GUI.Button (Rect (50,650,Screen.width - 100,100), "Davko")){
        
        }
        if (GUI.Button (Rect (50,750,Screen.width - 100,100), "Remi")){
    
        }
        if (GUI.Button (Rect (50,850,Screen.width - 100,100), "Míša")){
    
        }
    }

    if (form){
        vyber = false;
    }
}

Look at GUI.BeginScrollView. You could also save yourself some time using GUILayout.
