Removing columns

I am revising a document originally made using Word. It is in landscape with two columns to make it easier to print. I now want it to be portrait with one column. Can I change it to this?

Hello @RichardH Welcome to collabora online forums

Change to Portrait Orientation

  1. Open your document in Collabora Online.
  2. Go to the Format menu at the top.
  3. Select Page Style.
  4. In the dialog box that appears, switch to the Page tab.
  5. Under Orientation, select Portrait.
  6. Click OK to apply the changes.

Thanks,
Darshan
