How to hide "Help" and "References" menu tabs in Tabbed UI?

Installation & Configuration

I’m embedding Collabora Online in my web application using an <iframe> and the Tabbed UI mode. I’m looking to simplify the user interface by hiding some of the top-level tabs — specifically the “Help” and “References” tabs.

I’ve successfully used the postMessage API with MessageId: "Hide_Menu_Item" to hide menu items in Compact UI, like so:

{
  "MessageId": "Hide_Menu_Item",
  "SendTime": 1677600490227,
  "Values": {
    "id": "help"
  }
}

However, this approach doesn’t seem to work in Tabbed UI, and I haven’t found any documentation indicating support for hiding tabs in that layout.

  1. Is there any supported way to hide or disable specific tabs (like “Help” or “References”) in the Tabbed UI, either through postMessage, WOPI properties, or some other API?
  2. If not, is there a recommended alternative (e.g., customizing the source if self-hosted)?
  3. Are there any future plans to support this type of UI customization in Tabbed UI via postMessage or configuration?

I want to preserve the Tabbed UI for its modern layout, but reduce UI clutter for our users.

Thanks in advance for any guidance!

Hello @Doconaut Welcome to the collabora online forum :slight_smile:

I think you can use Hide_NotebookTab option to achieve your goal :bow_and_arrow:
