I noticed that in the official Retool templates, whenever there's a table of items, the detail view of each one is always shown on the side. I feel that's not the best way.
The details take space, making the table shorter and you have to scroll it horizontally if it has more than 4-5 columns. They also take away the focus as the user is now seeing 2 things at once.
Wouldn't a modal work better? What do you think?
