Flexlayout "type" values

Hi all,
I’m running some experiments with flexlayout.
I saw this snippet (https://snippet.webix.com/d53a25a9), mentionning

type: "wide";

In the same snippet, if “wide” is changed to “clean”, the background color is changed, but is it the only effect ?

https://docs.webix.com/api__refs__flexlayout_props.html
does not mention at all the field type.

Did I miss anything ?
What are the possible values and their effect, for this field ?

Finaly, I found this:
https://docs.webix.com/api__ui.layout_type_config.html

And it provides what I need.
