If there is a Sub-Section feature, that would help hide fields neatly.
For example:
1. We have a submission form with three sections.
2. Each section has it's HTML block to identify and group the fields together. Like Personal Details, Travel Details, Other Details etc.
3. We decided to add a fourth field DECELERATION on top with it's own HTML block.

Objective:
Create rules to achieve the following
1. If Deceleration field is blank, hide all the three sections below. (Okay that is achievable).
2. If Deceleration is Yes, hide section 3 "OTHER DETAILS".
3. If Deceleration is No, hide section 1-2 only and display section 3.

Issue:
We experience that the HTML blocks will remain visible some how which gets bit untidy.
