Currently, I’m using developer edition. Can i hide the toolbar in the red area by using DocsApi.
Hey @carl1 
If I understand correctly, this is what you are looking for:
You can also try applying these parameters directly on this page: Customization Settings.
Please review, and let me know if this meets your needs or if you have any further questions 
Thanks for providing that option. What about the status bar and 2 left and right panels, i wanna hide it by using settings

Hi @Eden
We are continuously working on improving our API for better integration — thank you for bringing this to our attention!
The link you are looking for is:
https://api.onlyoffice.com/docs/docs-api/usage-api/config/editor/customization/customization-standard-branding/
Unfortunately, the API is currently being transitioned, and at the moment, the ability to visually demonstrate parameter functionality is unavailable.
We are actively working on adding this feature back. Apologies for the inconvenience, and thank you for your patience!
In the meantime, you can use the following link:
https://legacy-api.onlyoffice.com/editors/config/editor/customization
This is an older version of the API, and it is no longer being updated. However, it still provides a way to visually explore parameter functionality for your needs.
