Hi all. I'm making an app which presents reading content to the user. I want to implement a table of contents navigation. I'm making my app Material Design, and would like the table of contents to be with that same style. How is it best to do this? I thought of a few options: 1. Navigation Drawer. 2. Expanding Custom ListViews. 3. CardViews. Any other ideas? What would look nice and be the most intuitive for the user? If anyone has any references to a sample, examples, apps, and images, I would be happy. I'm looking for ideas. Thanks!
