Fixing the addition of the playground

[kaushikc44]

1. I want to be able to add more playgrounds , but I don't want them to bundle up and have me scroll through them. I want to be able to access each of them in such a way upon clicking one text area on the side bar I can only see the text area of that particular field.
   Please visit the site for more reference.
   
   as u can see currently it has one text area. If I add an extra text area it will increment but I have to scroll down in order to view it.
   I don't want to scroll instead hide the ones I am not at and view the current one that I am focused at.
