I'm afraid I can't think of anything besides using HTML straight:

<details>

<summary><a href="https://www.youtube.com/watch?time_continue=1&v=eBGIQ7ZuuiU&feature=emb_title">Here is a nicely formatted hyperlink!</a></summary>

And it rolls well!

Can you add code inside the dropdown?

Can you add code inside the dropdown?

There's code inside this dropdown...

This is how you add code in a dropdown:

console.log("Hello, world!");

    <details>
      <summary>There's code inside this dropdown...</summary>
      <br>
      
      This is how you add `code` in a dropdown:
      ```javascript
      console.log("Hello, world!");
      ```
    </details>

@jeremy0x have you perhaps discovered a way to make the dropdown a header?

@AlexandreFPGoncalves Unfortunately, I haven't.

HTML header tags can do this.

It's true!

<details>
<summary><h1>HTML header tags can do this.</h1></summary>
It's true!
</details>

h1 through h6 are valid, just like one # to six ###### is valid.

Cool 👍 @EtiTheSpirit

Nice!

😄

That will do @EtiTheSpirit Thanks you! 😄

I made some formatted dropdowns on the GitHub profile for a game development project. They're centered, have images, and one has hidden tables.

Nice. Thank you! @cosmiccoincidence
