@KaelanKhiatani looks like some of my previous feedback is still pending - maybe because of our rebase. Can you incorporate that and push an update? You can commit directly from the conversation/comments above, or just make all of the changes locally and add a new commit

[edonehoo]

with v5, the "next" components are promoted, so this file is now contained here: https://github.com/patternfly/patternfly-react/blob/main/packages/react-core/src/components/Select/examples/Select.md

This is the link to the v5 page: https://staging.patternfly.org/components/menus/select

In VS code, make sure you're up to date with the 'main' branch and that the Select.md file matches what you see at these links, with the content you're adding. This may be something easier to look at together on a call?

& content is missing from a few examples, but if you need help drafting that just lmk!

We can do this tomorrow.
