How do I add collapsible elements?

I have dabbled with html in the past but Corvid is completely new to me. I have always always wanted to have collapsible elements on my websites but have never been able to do it. I then discovered you could using Corvid!

Wix gives an example of collapsing elements created using Corvid - https://www.wix.com/corvid/example/collapse-elements , but there are no step by step instructions in documentation. Looking at the code of the elements is also mind boggling not knowing what any of it means or is referring to.

Are there any instructions on how to create collapsible elements? Or can anyone explain (in simple terms!) how to do this?

With the tutorial that you have linked to: https://www.wix.com/corvid/example/collapse-elements , all you have to do is click on the button that says ‘Open in Editor’ and it will open up in Wix Editor and display all the elements on the page already setup for you, along with all the code setup for you as well in the page code tab.

With this you can look at how it is designed in the Editor and what code is used and then go over to your Wix Editor and start making up something similar to it.

If you are looking for a more detailed step to step description, then just search this forum through the magnifying glass at the top right, or simply look at other Wix tutorials or video examples:
https://www.wix.com/corvid/examples and https://www.wix.com/corvid/video-tutorials .

Or you can search for Wix Experts like Nayeli (Code Queen) and see if she has a youtube video to help guide you through it, something like this one here:

You could also cheat and use the Wix FAQ app and do it all without code:
