Assign a data-class to each item in the .screening-days list based on the corresponding unordered list, and utilize this JavaScript code for show/hide functionality. While the checkbox hack could be a more efficient solution (look it up), the focus here is on achieving the desired effect using jQuery.
HTML
<li class="active" data-class="mon-listings" id="monshowtimes">Monday</li>
<li id="tueshowtimes" data-class="tue-listings">Tuesday</li>
<li id="wedshowtimes" data-class="wed-listings">Wednesday</li>
<li id="thurshowtimes" data-class="thur-listings">Thursday</li>
<li id="frishowtimes" data-class="fri-listings">Friday</li>
<li id="satshowtimes" data-class="sat-listings">Saturday</li>
<li id="sunshowtimes" data-class="sun-listings">Sunday</li>
CSS
.movie-timing {
display:none;
}
.movie-timing.show {
display:block;
}
JS
$('.screening-days li').click(function(){
$('.screening-days li').removeClass('active');
$(this).addClass('active');
var dataClass = $(this).data('class');
$( '.movie-timing' ).removeClass('show');
$( '.movie-timing.'+dataClass ).addClass('show');
});
