Unity 5 Closing Menu On Multiple GameObjects When A New Menu is Opened?

Question

I am trying to make a menu system for each GameObject, and when a GameObject is clicked it will close all other menus and open the one for that GameObject. I am using one script for this:

using UnityEngine;
using System.Collections;

public class BlockMenus : MonoBehaviour 
{   
Vector3 point;

public Transform block;
public GameObject activeBlock;

bool buttonActive = false;
bool activeBlockActive = false;

string hitObject = "";

void Update()
{
    point = Camera.main.WorldToScreenPoint(block.position);
}

void OnMouseDown()
{
    hitObject = this.gameObject.transform.tag;

    buttonActive = !buttonActive;
    activeBlockActive = !activeBlockActive;

    activeBlock.SetActive(activeBlockActive);
}

void OnGUI()
{
    if(buttonActive)
    {
        switch(hitObject)
        {
            case "mine":
                GUI.Box(new Rect(((point.x) * (1.08f)), ((Screen.height - point.y) * (0.1f)), (Screen.width * (0.3f)), (Screen.height * (0.5f))), "");
                GUI.Button(new Rect(((point.x) * (1.08f)), ((Screen.height - point.y) * (0.87f)), (Screen.width * (0.05f)), (Screen.height * (0.06f))), "Build Mine");
                break;
        }
    }   
}
}

This may work/help. The best solution I can muster/find is toggling the GUI objects individually and not just setting them all at once. You don't need to do it in a switch really. This is a mix of your code and the solution I found.

using UnityEngine;
using System.Collections;

public class BlockMenus : MonoBehaviour 
{   
    Vector3 point;

    public Transform block;
    public GameObject activeBlock;

    bool buttonActive = true; 
    bool activeBlock = false; 

void Update()
{
    point = Camera.main.WorldToScreenPoint(block.position);
}

void OnMouseDown()
{
    buttonActive = !buttonActive; /* Turn button off */
    activeBlock = !activeBlock; /* Turn block on */
}

void OnGUI()
{
    if(buttonActive) /* Button is live */
    {
       GUI.Button("Button"); /* Put button specs in */
    }   
    if(activeBlock){ /* Block is live */
       GUI.Box("Box"); /* Put box specs in */
    }
}
}

Also I realized the need to use the !. Makes sense if you are only using the mouseDown. Alternatively you could add an opposite mouseUp to swap things back, but both should do relatively the same thing. Although if you use the mouseUp you may end up with a very fast switch every time you click.
