Repeatable Text Field Option Layout

[sebcoetzee]

I made an option for a repeatable text field. Everything works and I have tested it but I don't know about the layout. This is what I currently have:

I have to decide between having fields that are repeatable under a main heading (Contact Text in this case) or having the main heading and a single text field be repeatable. I'm not exactly sure how to repeat the main heading since it is inserted using the echoOptionHeader() method. I suppose I could pass the heading text to the javascript and then add it dynamically when the button is pressed.

Please let me know what you guys think.
