Is your feature request related to a problem? Please describe.
When the someone else(usually frontend developer) using the swagger to integrate the server-side API into the frontend project, but the input/output definition model description is too hard to use, because the users should click the definition(include nested model & fields) one by one to show the comment.

Describe the solution you'd like

Could we add a one-click expand button to expand them all? To avoid the structural level to high，limit a max size?

Describe alternatives you've considered
