Below is an example I created using a non-responsive workaround.
I am aware of the existing workarounds that include
checking "enable shadow" on shape and vector elements
using a line and customizing its design to the shadow preset
uploading my own transparent shadow PNG and placing it behind the column (what I've done in the attached screenshot)
None of these are responsive to allow predictable placement of the shadow on varying screen sizes. So it would be awesome to apply the shadow directly to the column!
Thanks for reading!
