I know you are all very busy but just wanted some quick help (hopefully).
I swapped out the current slideshow particle to use Smart Slider 3 - i really like that slide show component as it is very powerful.
In any case i replaced the current slideshow but it looks like it goes behind the menu on the right which causes issue as some of the slideshow is lost and when you close/open the menu it can cause the slideshow to not fit correctly.
Can we get the slideshow so it doesn't go behind the menu but basically starts from where the menu ends?
Hope that makes sense.
I have uploaded a copy of the site and added details below - i am still working on a local version.
