• Hmm, let me see if I can find a better solution. The technical trick behind those folded sections is that they do not require any JavaScript. I.e., you will get the same experience even with JavaScript disabled.

    In addition, I will also have to find a solution for smartphones and tablets which do not have the notion of "hovering".

    Ok, I just added some downwards pointing triangles to the chips and removed the cursor from expanded sections - better now?
