In this chapter, we learned how to implement an advanced dynamic menu using an Accordion layout and also TreePanels for each module of the application. We learned how to handle the dynamic logic on the sever side and also how to handle its return on the Ext JS side loading a Store to build the menu dynamically. And finally, we have also learned how to open an item from the menu programmatically and display it on the center component of the application. We also used the MVC architecture for the first time.

In the next chapter, we will learn how to implement screens to list, create, and update users and also how to assign a group to the user.
