The composite is a design pattern that is tailor-made for creating dynamic user interfaces on the Web. Using this pattern, you can initiate complex or recursive behaviors on many objects with a single command. This allows your glue code to be simpler and easier to maintain, while delegating the complex behaviors to the objects.
