Sorry, this was a bad question. I couldn’t work out how to delete it. Actual question and solution here:

jQuery – Toggle div class on click

Answer 1

There is no need to rebind functions.

Either you bind the click event to a function called toggleSection() which hides the section if it is visible or shows if hidden, or just use this:

$('.section.hidden').click(function() {
    $(this).toggle();
});
