Show/Hide subform using buttons

Hi,

I am new to the "LiveCycle Designer". I want to create a form which has 4 Sections "Experience", "Skills", "Education Details", "Personal Details". Based on the below screenshot the sections are formatted and the main sections are created as subform ("ExpForm", "SkillsForm", "EDForm" and PDForm").

Each sections has 5 bullet points and that I created as separate subform ("ExpSubForm", "SkillsSubForm", "EDSubForm" and "PDSubForm") and these subforms are hidden. So. when we click the experience section "Plus" button the hidden subform should be "visible" and the skills should automatically goes down likewise I need to do for all the four main sections and the user click the "Minus" button the visible bulleted subform should be "hidden" and skills should automatically goes up.

Kindly do the needful.

Thanks in advance.
