Dynamically adjusting width of container from function
I'm using a script Custom Content Scroller to create a sliding div with a customisable scrollbar. It's almost perfect for my needs and I've written a function to hide images within the scrolling area when a user clicks a category to hide it.
This all works fine and when some of the images slide-out the horWrapper div resizes smaller to fit the smaller number of images being contained. However, the reverse is not true. When the images slide-in, horWrapper does not resize and the returned images cause wrapping within the content container.
Looking at http://manos.malihu.gr (scrollbar plugin's home), $.fn.mCustomScrollbar.CustomScroller(); should refresh the slider, and it probably does. But it does not refresh horWrapper. I'm sure there's something within the plugin code that I could use to refresh the width of horWrapper, but I can't see how I'd implement it. Assistance would be much appreciated! I've been struggling with this for several hours now.

I got this working in the end. Irritatingly, the answer to this problem was listed within the numerous comments of the original blog post.
[EDIT Dec 2012]: For anyone else who is having the same problem and is unable to get to the comment/solution referred to above for whatever reason, here is solution provided by the site owner/script developer:
Firstly, get the plugin file: http://manos.malihu.gr/tuts/jquery.ba-resize.min.js and put it in the directory of your document. In the head of your document, before the closing head tag add: <script src="jquery.ba-resize.min.js"></script> At the bottom script, below your LoadNewContent function add: $(".content").resize(function(e){ $("#mcs5_container").mCustomScrollbar("horizontal",400,"easeOutCirc",1,"fixed","yes","yes",20); });
With this, you can remove the other callback functions calls of mCustomScrollbar.
