Hi Zaid,
Our Infinite Openings tools allows any number of sliding panels on either side with fix panel, face slider, and cavity slider options.

There are several videos on it here:

None of the videos show the multi-slider except briefly in one of the latest:

I don't know of any other object that will allow more than 3 sliders, hence I built the ability into my own tool.
