Presently, when I place a bootstrap drop-down inside a cell the drop down is cropped when open (it is hidden behind the rows below). 

Can you please endeavor to eradicate this issue within your components so that we don't have to jump through lots of "css hoops" or worse "write jquery to do it" in order to get the desired result. 

Your components should be fully compatible with bootstrap (since you have a BS theme and lets face it, its pretty well industry standard these days)

Many of our "grids" require an Action column which in some cases has more buttons than we would like to put "side-by-side" and so the best option is to add a drop-down action button to hold the action commands.

At present there is no equivalent Kendo component that will do this for us either. Your grid cells should really cater for this as other users may want a custom column with "drop down" content too.
