Hi all!

Is it possible to build dynamic edit/add-Forms for custom blocks? I would like to create a custom form with a variable number of form elements depending on user input. New input elements will be added by the user (by actual jquery calls).
I want to aggegate data from several input elements into one data field of the data table which requires pre/postprocessing on the form, but up to now I was not able to figure out where to insert within the framework.
Any hints will be appreciated!
