Looked At DoJo. There is, of course, have everything you need. But I now have no month to study this system. Besides, our system of administration of such design that it is not possible to use ready-made visual components that DoJo provides. So the whole point is lost. Same story with YUI.
You need a tool that will manage the interaction of ready-made visual elements (which are written using a large number of jQuery and plugins).
From the server I am receiving a json, which laid out all the necessary information of the edited object. Yet there are a few additional json-object with values for all drop down lists and forms with autocomplete. Need to return json with the same structure. Inside the form actively used by drag&drop. No page reloads are not happening.
Links to examples of good interfaces, too, would be useful. Thank you.
