Still can not solve the problem.
How to make "left_side" increased along with "right_side" if it adds a line of text?
And how to make in the column was not more than 4 cells, or after a certain height, there was a shift to the right?
And lastly, after adding "float: left" sortable ceased to run properly...
Pomozite with the decision in the frontend is not strong, but piled up the task along with Beck.
