‌‌How to create 2-column, 3-column, etc. horizontal multicolumns?

‌‌‌Currently, all content is arranged from top to bottom and the layout is not visually appealing. I hope it can support multiple columns in one line, like Notion, as shown in the picture.

‌‌‌‌I found a previous push, although it doesn't have Notion's practicality, it has basic functionality, I'm not sure why it wasn't merged.
