Hi Hugo,
Welcome to the Coda Community!
Short answer - No. You do not have collapsible rows in tables in Coda.
But you do have
- Nested pages
- The ability to have nested tables, which has just had a big new announcement of improvements.
- There are packs that will assist in various ways, from using AI to create a mindmap, to Mermaid allowing you to use it to create different kinds of graph based layouts.
- The ability to cross reference entries in a table to itself. This can be used to create a hierarchical structure like below:
And below is a link to the above page:
I mean the next in the best possible way - Coda is very different to anything else. Even to Notion, even though superficially they look similar. Looking for features from Notion, Airbase, Excel or other apps is going to be an exercise in futility and frustration.
Take a month or so to get to a good understanding of Coda, and then build your magnum opus. If it is a magnum opus, it will be worth the extra upfront effort.
