I've added tabs here for you in case you want them. The coding for tabbing is simple; all you have to do in the future if you want to add more tabs in a tabview is use the code

[[tab Title of the Tab]]

[[/tab]]

And that's it! Furthermore, if you want multiple tabviews (as seen in my own sandbox), you can use
[[tabview]]

[[/tabview]]

Of course, if you dislike tabs, feel free to get rid of all of this and format it whatever way you want. Cheers!

As for collapsibles, you should use;

[[collapsible show="Words for opening text" hide="Words for closing text"]]
Your text
[[/collapsible]]
