Recently, Capybara with Selenium driver was not able to see a given css element. Trying without the driver works though.
As it turns out, in my case, the css element was hidden. And Capybara by default cannot see hidden elements.
There are two ways to go around this:
a. Set Capybara global options to view hidden elements
b. Set particular DSL option to see hidden elements
select "hello", from: "Some question", visible: false
