This is an addendum of a previous question: How to put a box and use columns to separate arrows.

Please consider this MWE (adapted from a nice answer of that question):

It works fantastic.

Now I want to add another arrow, that goes from (2) to (3), so one would probably add

"{3}",

to the LstCon object (please increment the value of totalnodes by 1!), but this produces an ugly output, because it collides with "Subject1".

To fix this, I have been told that I need to create this new arrow outside the foreach loop that it is inside the tikzpicture environment. So I have deleted "{3}", and added the following three lines to the code:

pgfmathsetmacro{huenumm}{2*0.75*(1/totalnodes)}

definecolor{mycolor2}{hsb}{huenumm,1,1}

draw[-latex,mycolor2,very thick] -- ++ (3,0) (2-Title.east) to[manoooh curve=1.6] (3-Title.west);

You only need to uncomment that lines of the given MWE to get this output:

It looks like there are no problems.

However, adding that arrow outside the foreach loop makes the checkbox of it non-clickable:

I want to make it possible to click on this new checkbox. How can we do it?

Thanks!!

P.S. Also I am getting an overfull hbox bad box message because of the parbox. Could you consider try to find out why I am getting it?
