ExtJs has rich layouts functionality. In this post I will show you how to make reflowable vbox layout. Reflowable layout is very useful in resizable components i.e. popups and splitted subcomponents.
Storing field values in cookies maybe useful not only during the debugging/developing the app but also for users who can continue working on the same browser next day.
Another method which makes user’s life lighter is to implement form template mechanisms. Users will be able to store some form states on the server and use them later.
Server side field validation can make the filling process of the form faster. It will show the incorrect form values on the fly. Remote validation must be done only in case when it is impossible to produce it on client side.
