__NOTOC__
  
A toggle button is a button which stays down when clicked once and goes up when clicked a second time.

+
==When to Use==
+
 
+
Use a toggle button to indicate a '''state'''.
+
 
+
Example: A word processor should use toggle buttons to indicate the state of "Bold", "Italic" or "Underline" formatting.
+
 
+
==When not to Use==
+
 
+
Do not use a toggle button to indicate an '''action'''.
+
 
+
Example: A music player should not use a toggle button to implement a combined Play/Pause button. It should use a normal button and adjust the icon and label to represent the action which would be performed when clicked.
+
 
+
==Icon and Label==
+
 
+
There are two ways to label a toggle button:
+
 
+
'''1. Describe the state which is reached when the button is down'''
+
 
+
In this case the icon and label should not change when the button is down.
+
 
+
For example a button to toggle the visibility of a sidebar could say "Show Sidebar". It should still say "Show Sidebar" when the button is down: it should not be changed to "Hide Sidebar".
+
 
+
If you want to change the button text to "Hide Sidebar" when the sidebar is shown then you should use a normal button, not a toggle button.
+
 
+
An alternative is to reduce the button to a noun if it is not ambiguous. In this example the button label could be reduced to "Sidebar".

+
'''2. Describe the current state'''
+
 
+
In this case the label will often include a passive verb. For example a button to lock or unlock an element would say "Unlocked" when it is up and "Locked" when it is down. The icon should match the label.
