Trouble when having so much li tags?

[Felipe ou Jimmy]

Hey everyone I'm doing an experiment using https://api.rubyonrails.org/.

For that, I'm trying to get all the li inside this ul

But if I do something like

page = agent.get('https://api.rubyonrails.org/')
puts page.search(".tree")

I only get a empty ul

Is there a size limitation or something? I don't get why It does not return all the li.

Just figure it out that this ul is populated with JS after, closing the issue
