The title may be misleading but basically I'm trying to give my character a feat and I go to features and Traits and click on manage feats and there is literally only 2 feats I can choose from/ appear. I have the prerequisites turned off aswell  but nothing pops up. I'm pretty new to this so if im missing something let me know.

If your wondering, the two feats that appear are Grappler and Svirfneblin Magic.

Grappler is the only feat free in the SRD and Svirfneblin Magic is part of the (also free) Elemental Evil Player's Companion. Have you purchased the player's handbook (that contains the majority of the feats) or any other feat sources?

Sounds like you are missing all the feats in paid content. Have you bought content on DDB or had it shared to you via a campaign?

The Player's Handbook is not free content.

The (Free) Basic Rules (SRD) only includes a single feat, grappler. Other feats must either 1. be purchased as part of a book, 2. purchased individually, or 3. shared using content sharing by someone with a Master Tier subscription

I see I didn't realize. Thanks for letting me know, I'll just apply the effects manually then.
