Quick answer
Post flair is a label that appears on a post, usually chosen from options the community's moderators define. User flair is a different label that appears next to usernames. A community can require post flair, make it optional, or not offer it at all, and moderators control the available options. When a required flair looks greyed out or missing, do not guess: check the community's posting page and visible rules, and read any message Reddit shows before submitting.
Post flair is a label a community can attach to posts, often chosen during posting. It is defined per community by that community's moderators, not by your account settings.
Post flair and user flair are different labels
Post flair is the label attached to a post, such as a topic, question type, or launch category. User flair is the label that appears next to usernames inside a community. They look similar and are both defined by each community, but they serve completely different purposes.
When a posting page asks you to choose a flair, it is asking about the post. Do not confuse it with the flair next to your username, which is set through the community's own user-flair controls and may follow different rules.

If a tutorial tells you to add flair without saying which kind, confirm whether it means post flair or user flair before changing anything.
Where flair options come from
Communities define their own flair options, and moderators can make post flair required, optional, or unavailable. That is why the same label you used in one subreddit may not exist in another, and why a post that fit one community can require a completely different flair in the next.
When you open the posting page, the flair selector shows the options the community currently offers. Treat the list you see as the source of truth for that community, not a list remembered from another post.
When flair is required, missing, or greyed out
A community can refuse to let a post through until a required flair is chosen. If the selector is empty, greyed out, or does not offer a label that fits, do not submit with a wrong label or try to bypass the requirement.
The right move is to stop the draft, re-open the posting page, and look at what it shows. The options may have changed, the post type may not support that flair, or a rule may explain which label is expected. When the page itself offers no answer, check the community rules or ask the moderators briefly instead of guessing.

Flair is a format check, not a rule exemption
Choosing the right post flair removes one formatting mistake. It does not change whether the topic fits, whether links are allowed, or whether the post counts as self-promotion. A correctly flaired post can still be removed for other reasons.
Use flair as one item on the posting checklist: topic fit, post type, title format, flair, link and promotion rules, then Reddit's native final messages. None of those steps replaces the others.

A community that offers a promotion or feedback flair is still not blanket permission. Its other rules and moderator judgment still apply.
