To get a box shadow on a shape element:

Add the shape class to the element’s CSS Classes. For this one we’re using

polygon-bottom-right

Add a filter:drop-shadow to the COLUMN that the element resides in.  For this drop shadow we are using

filter:drop-shadow(0px 5px 5px rgba(0,0,0,0.2));
 -webkit-filter:drop-shadow(0px 5px 5px rgba(0,0,0,0.2));
