Expandable settings: how?

[Giampi71]

I'm building my first clockface with settings, a very original one  with selectable colors. 

I saw some other apps using settings that expand with an arrow button that if pressed expands the settings below (Hopefully it's clear, I don't know how to explain better).

Is anybody helping me?

Thanks

Have a look at the Toggle examples at https://dev.fitbit.com/build/reference/settings-api/#components

With a bit of mucking around, you can get multiple items to appear and disappear. They can respond to settings changes made in companion .js code, too.
