# compose

I've recently gone though the full compose codelabs and I got a few questions that got me stuck in development:
• How can I focus next TextField? Changing IME action wasn't enough, I'm not sure how to use the (experimental) focus API
• Is there a way to use error property in TextField? Do I have to create one manually? I was using OutlinedTextField
• Is there a list of all available components somewhere? Looking through sources of sample apps seems less than ideal when looking for something

1. See Jetchat we use the focus APIs. See focusRequester and focusObserver

3. We were thinking about creating a widget catalog but it slipped as it would be hard to maintain in alpha with all these changes happening

We don't need a catalog with live examples, I think a list of UI components (functions) would be great for the beginning.
E.g. I wanted to create a divider, struggled 10 mins on it and then realized there is already one.

It is hard to get know what's possible when it is in different packages.

[ppvi]

yeah fair point

[Zan Skamljic]

Absolutely agree with Jan on this, for now a simple list would do, as long as I don't have to open up a repository or something to view all files in a package
