Floating Menu with Page Anchors in 7.1

Hey everyone!

Im have to do a page for a website, and I want to display many youtube videos as cleanly and easily updatable as possible. They have to be arranged by Year and Event, so I really wanted to have a floating menu (like the one on the right of the page in the help guide of squarespace https://support.squarespace.com/hc/en-us/articles/207135178-Creating-anchor-links) organized by categories like:

2023

        Event 1

        Event 2

2022

        Event 1

Also, how can it work in a mobile setting?

Thanks so much! 😄

My ideal is you can add a Text Block (1 Text Block) with Unorder List, then we can give code to style it & float it to right of site

2020 text

• Event 1
• Event 2

2022 text

• Event 1
• ..

That would be perfect! Thanks Tuanphan, i was hoping you could pass by my question! 🙂

Can you help me with the code to make it float and the page anchors on the unorder list? 

Thanks so so much, and sorry for bothering!

@XTC,

Just to speed up the process between Tuanphan and yourself, include a link to your page.

Thanks Alex! However im still building the webpage, because if I cant do it with the floating menu, ill have to rethink my strategy, so not much to share just yet!

But you can access the webpage here: https://oval-buttercup-jraf.squarespace.com Password 1234
