Is it possible in IP16 to build a dynamic form applet?

The idea of having a script to hide some fields based on rules (that you can read from calculated fields) is not new, and is doable. However, hiding a control could be done in two ways: Either keep its place empty, or shift the other controls to the left. I can do that in JQuery, but the client did not like that

Instead, the client wants a solution by assigning an "Order#" to each field on the applet. Then to put these fields on the form applet on the fly based on the Order#.

That sounds possible in theory, but could that be done practically?
