libreoffice draw view layout greyed out

I would like to see my many pages in draw under each other in the main screen instead of having to click each page in the preview page.

I have searched and found that “zoom & view layout” would do what I want but the view layout section is greyed out.

How can I fix this?

The help describes:

"View Layout -
For text documents, you can set different view layouts. Decrease the zoom factor to see what the individual layouts do. "

If I understand it correctly, it means text documents, PDF files opened in Draw.
This option is not available for normal slides in Draw, so “view layout” is greyed out.

If this is important to you, you can submit an amendment to Bugzilla. It should be detailed, and shed light on why such a function is important.
