Hierarchical tags : how to select all parent tags by selecting a child tag ?

Hi !

I haven't yet found how to select parent tags by selecting a child tag.

I've read in a tutorial that it can be set by Digikam settings / 
metadata / information writing in metadata

by selecting Parent instead of Toggle Auto which is the default setting.

The problem is that I can't see this option.

I use Digikam 8.8.0 on Kubuntu 24.04 LTS.

Thanks for helping.

Regards.

Pierre
