In this chapter, you learned about forms and the basic fields that you can use to collect and edit data. We have many options and configurations available, and we can use them to customize our forms. The field container is one of the new components added since version 4 of the Ext JS framework, and it allows us to arrange fields using any of the available layouts in the framework, giving us a powerful layout system.
You also learned about the new trigger configuration on text fields and how to submit data.
In the following chapter, you will learn about the grid component. This is one of the most powerful widgets in the framework because it's very flexible, with lots of plugins and configurations.
