Libre_Writer toggle expand/collapse all headings

I have enabled toggle “Outline folding”. How can I select multiple headings and collapse/expand simultaneously ? for example how can i select “Day26 - 236” , “237” and “238” and collapse/expands them simultaneously ?

“Day 26 -233” is H1, and all subheading are H3 .

Thanks

You can’t. You must click individually on the node control or click on the upper level control but this is probably not what you want.
