Dear David, All
Yes i do have a good reason, imagine you have multiple baskets which
can be for example type of rooms in a hotel e.g average one bedroom,
master sweet or a case where a university has multiple students. For
easier management of resources [hotel equipment or student courses]
the administrator can drag drop. However i'm open to criticism and
suggestions on how to have multiple scrollable baskets in a div or
otherwise.
i believe as complex it might be it can be good example for fellow
colleagues, students hoping to forster creating of remarkable Desktop
like javascript, web based applications. Checking protype.js and
dragdrop.js to better understand this.
Thanks you for your time.
Isaac
