Move UI panel on and off screen, scripted without animation

I have a menu on the left side of my screen that is currently showing. It is a Canvas with a Panel object, a Text object, and some Button objects. I would like the Panel and all its Buttons to be off screen when the game starts. A portion of the Panel and the Text, which is vertical and says "Menu", will be showing. When the player clicks the "Menu", I would like the panel to move onto the screen, showing all the buttons. Another click on the "Menu" text would move the panel and the buttons off screen again.

I have an Event Trigger on Pointer Click set on the "Menu" text. I have a script called "ToggleMenuUI" as a component on the Panel. The Panel is the Object in the "Menu" text Event Trigger using a public function called Toggle() in the script. What am I missing to make this setup work?

UPDATED: Figured it out! I had to use the anchoredPosition property rather than the position property.

Here is the (working!) script, kept up for helping others: using UnityEngine; using UnityEngine.UI; using System.Collections;

public class ToggleMenuUI : MonoBehaviour {

 private RectTransform rt;
 private Vector2 open;
 private Vector2 closed;
 private bool IsOpen;

 void Start () {

     rt = GetComponent<RectTransform>();
     open = new Vector2(-5.0f, -5.0f);
     closed = new Vector2(-82.0f, -5.0f);
     IsOpen = false;
 }

 public void Toggle () {

     if (IsOpen)
     {
         rt.anchoredPosition = closed;
         IsOpen = false;
     }
     else
     {
         rt.anchoredPosition = open;
         IsOpen = true;
     }
     
 }

}
