Indesign and pdf forms - is extended conditional formatting possible?

Hi,

I'm trying to figure out if and how it's possible to make extended conditional formatting work on pdf forms through indesign.

So it's possible to create actions on form elements to show/hide other form elements...

I'm trying to show a hidden section of questions upon answering "yes" to another. We can use form actions to show/hide the form textfields. Easy. But can we also show/hide the textlabels that are used as labels for the textfields in the hidden section? My question would be: can we make textlabels show/hide and make the rest auto-reflow?

How would we do that? I was asked to make a huge form, which is absolutely needed in a pdf, it would make sense for me to make it conditional in a few places. Is this possible? Some of the features found in Indesign would make you believe so, but i guess they are limited in several ways. Documentation is present, but not really extensive or thorough enough for what i'm trying to achieve, if at all possible.
