I would like to add a set of checkbox'es from ocgx2 package, where we can set the arrows to "Visible" or "Invisible" that connect two or more subjects:

If we deselect e.g. "Correlatives of subject C" then all the arrows that start from "Subject C" must be changed to "Invisible", so we cannot see them. Also the "Select All" checkbox has to change, meaning that "We have not selected all the checkbox'es" i.e.:

If we deselect all of them:

Note that the "Select All" checkbox is automatically changed due to the user's deselection of all the other checkbox'es.

As expected, the user can select "Select All" to make all the arrows visible. If he deselects it, all the arrows must be invisible.

You can rely on this great example of AlexG's comment:

documentclass[12pt,margin=3pt]{standalone}



usepackage[tikz]{ocgx2}  % PDF Layers

usepackage{amssymb} % checkmark

  % #3: initial visibility

  resizebox{2ex}{!}{ooalign{%

    switchocg{#2}{$square$}cr%

    begin{ocg}{#1}{#2}{#3}$checkmark$end{ocg}%

  }}%

}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



begin{document}



begin{tikzpicture}

  node (a) at (0,0) {A};

  node (b) at (1,1) {B};

  begin{scope}[ocg={name=Arrow,ref=myArrow,status=visible}]

    draw[->] (a.east) -| (b.south);

  end{scope}

end{tikzpicture}



layerCheckBox{Arrow}{myArrow}{on}A$rightarrow$B



end{document}

If possible, the addition of the checkbox'es should be automatic, in the sense that if there is a set of arrows then they will be inserted in a new line of the big black frame.

After the compilation all the checkbox'es have to start "on".
