This UI component hasn't been finalized yet. The functionality and syntax aren't stable and might be redone in an upcoming release. Only use it at your own risk - breaking changes are likely to occur.
The Column component can be used within a Grid component to layout elements in a very convenient way. The Grid is based on 12 columns by default and each column can change its width with the width property:
Whether the column should stick to the window edge when scrolling
1/6, 1/4, 1/3, 1/2, 2/3, 3/4, 5/6, 1/1
Width of the column in the grid
The grid takes care of the responsiveness of the elements and also of wrapping lines automatically.
