Could you tell me the code to add the rsActiveSlide class to the previous and next image of the active image in the carousel slider? I'm trying to achieve the effect shown in the attached image. I've tried using .next and .prev jQuery but was unable to get it to work, could you point me in the right direction?

    There is no such option, you'll need to do this manually via slider JS API -

    Consider implementing such layout just via CSS by placing some transparent bars over right and left side, or use this technique

    Hi Dmitry,

    Would I use the following code to add class rsActiveSlide to the immediate previous and immediate next slides?

    jQuery(document).ready(function($) { "rsActiveSlide" )

    No, use events like rsAfterSlideChange or rsOnUpdateNav, or rsBeforeMove. To access content of slides you may use slides array, each its item has content property.

    $('.royalSlider').data('royalSlider').slides[0].content // content of first slide

    Hi Dimitry,

    I've tried multiple methods to add the class .rsActiveSlide to both the previous and next slides. Could you provide me with the jQuery code to do so?

    Thank you.

    Please post the code that didn't work for you and I'll take a look what's wrong.

    I used a lot of different combinations that I did not get a chance to save to a text file and did a lot of research on stackoverflow and google, but most recently I have up:

    'jQuery('#new-royalslider-1').rsAfterInit( function(){ jQuery(this).addClass('rsActiveSlide') }, );'

    You can see what I'm attempting to do at The first slider. The next slide and previous slide before and after the rsActiveSlide should also have the rsActiveSlide class.

    I know it's missing, I'm running off only a few hours sleep in the past few days so bare with me. I'm stumped so I really appreciate your help.

    Thanks for your help.

    Here is example for one slide:

    var slider = $('#new-royalslider-1').data('royalSlider'),
    var updateClasses = function() {
         // slider.currSlideId - is current index
         if(prevIndex) {
              slider.slides[ prevIndex ].holder.removeClass('rsActiveSlide'); // remove class from prev slide
         slider.slides[ slider.currSlideId ].holder.addClass('rsActiveSlide'); // add class to current slide
         prevIndex = slider.currSlideId;
    slider.ev.on('rsAfterSlideChange', updateClasses);

    Also, I'd recommend to disable default add-active-class feature, so it won't conflict with your implementation.

    If you're not experienced in JS, consider hiring a dev.

    Great, thanks. This is getting me almost there. Just one thing, I'm getting an error in FireBug "TypeError: slider is undefined". I'm searching for a fix but can't seem to come up with anything yet, any ideas? I tried loading the script as the last script after the slider has been loaded, I even used several different classes and ID on the var slider line

    #new-royalslider-1 .new-royalslider-1 .royalslider

    You're running the code before slider is initialized
