I'm getting frequent questions about whether Grid can handle a Masonry style layout using auto-placement.

You can see a good example, along with some author use cases here.

Currently the closest you can get with CSS to this type of layout is to use multi-col however the items then flow top to bottom rather than across the rows.

This feels more like a behaviour of flexbox than grid, as the solution is very much based on the size of the items. Opening this in order to record the feature request/use case for future discussion.
