I've included a JSFiddle link below to see my code. The code creates 6 boxes, 3 on top of the other. However, I'll eventually want to input a new box BETWEEN one of the others. Currently, this causes one row to have 4 boxes. What I want to happen when I insert a new box is to SHIFT the box to the right. So if I insert a new box between Box #2 and Box #3, I want Box #3 to take Box #4's current position, ultimately pushing the current Box #6 to start a new line by itself.
Please tell me how to do this and/or provide code example.
Thank you so much!
