The example looks good! A couple small things to add/change:

• update the number of examples from 1 to 2

• build out, publish, and link to the example in the pattern library in Figma, and add the Figma link to the example heading (let me know if you have any questions)

Good catch! I've amended my commit wit the following changes:

• Changed the tab number from 1 to 2
• Added the link to the Figma example

I also realized that "long-answer question" should include a hyphen. I've added one.

Looks great now, thanks for making those changes.

One more consideration:

When filling in the text area it's not a lot of working area to show 500 words, it has to scroll fairly quickly and the input stays the same height, limiting the view. It would be nice to add a grab bar on the edge of the text area to drag it taller, or even have it auto size, like this issue: GovAlta/ui-components#1568.

In the meantime for this example, maybe we should start it as 5 or 6 lines tall just so it has a bit more room?

@twjeffery Thanks! I've increased the textarea height to 6 rows. 👍
