@Brian_Radspinner I will try what you have told.
I will show what I am trying to implement. Take a look at this wiki. Here there is a viewtoolbar button which add a field called class to the tiddler with field value multicol2. What I want is on the second click of the same button, the field value to change to multicol3 and on the next click to multicol and on the last click to delete the field.
I have seen something similar in this muuri add on button by @fastfreddy
