Hi dotCMS community 👋 ,

I’m testing dotCMS for our project and have two quick questions:

1. **Layout Customization:** How can I enable CSS class autocompletion for users when editing layouts? I followed [the docs](https://dev.dotcms.com/docs/designing-a-template-with-a-theme#ClassSuggestions) but couldn’t get it to work.

2. **Keycloak Authentication:** I tried [the OAuth plugin](https://github.com/dotcms-community/plugin-dotcms-oauth?tab=readme-ov-file) (I use Keycloak for central auth), but it didn’t work out of the box. Should I build a custom solution, or is there a better approach?

**Details:**

- dotCMS version: 25.07.10\_lts\_v4

- docker compose

Thanks for any tips or experiences you can share!

Best, Simon

Hi Simon, apologize for the delay in response. I reached out to the engineering team to get you some answers and they will respond in the next day.

Hi Simon, on the second one - Will took a look and his advice is to take the OAuth plugin and customize it to your specific need. The other approach you could take is to use Keycloak + SAML. Hope this helps, let us know how it works out and if you run into other issues here.

Regarding the first question, Jalinson will post a video soon that should help you out.

Cheers,  
Marc

Hi Simon, I recorded a short video of how to setup the autocomplete for style classes on the layout editor.
