Feature Request: collapsible sub sections

[bhhaskin]

Be able to create collapsible sub sections under repeatable. It looks like this might have been planed at some point according to issue #33

I have created an overlay plugin that allows you to collapse repeater fields (all or individual) - https://github.com/meatHucker/simple-fields-minimizer
