+### Group
+
+If you want to activate/deactivate a set of constraints in response to some events, you can use `group()` to collect constraints into an array.
+
+```swift
+let constraints: [NSLayoutConstraint] = group {
+    view1.bb.fill()
+    view2.bb.left().top().size(100)
+    view3.bb.fillBottom().height(100)
+}
+```

 ## Manual Layout
 
 Why manual layout when there is Auto Layout? Well, Auto Layout is good, but it has some performance issues, that’s when you may want to switch to manual layout.
