drag and drop > ajax ?


I want to develop a interface like Igoogle, where visitors can organize
the elements on there webpage.

Wich helper must i use to realize this....is this act_as_list? or
another solution?


This may depend on lots of details of your implementation.
acts_as_list is more a database thing, to keep
your items as a list. Not exactly IGoogle.

draggable_element & drop_receiving may be of some help,
but still you'll have to do a lot of pure javascript programming.
