Show select boxes/options sequentially

Hello there,

Thank you for taking your time to read this. For my thesis, I want to compare two interfaces where one displays all options and the other displays one option at a time. The interface in question is for customizing avatar.

Following a tutorial online, I currently have the display all options deployed on streamlit sharing. Here is the associated github repository.

I want to create the exact same interface, but now with the customization options showing one at a time by clicking a ‘next’ (and ‘back’) button. This new interface will be deployed in the end as well, so I’ll have two links to send to participants.

I am quite inexperienced with programming in general, and after many trials and errors, I would like to ask what would be the best way to achieve this.

Thanks in advance!
