Expandable text-box, movable text, show/hide function

Hi there,

I am brand new to LiveCycle and have some questions. I have already stumbled upon some threads that deal with expandable text-boxes and I have "tackled" the issue, however, is it possible when the text box expands that the rest of the text in the document (in a form, in my case), expands as well?

And another thing, if I I have two drop-down menus/lists, say List A and List B, and I choose one of the options from the List A drop-down lists, is it possible to hide the List B when one of the options from List B is chosen?

Thanks in advance!

Best,

Mirza
