In a prior manual https://koha-community.org/manual/16.11/html/ch12s04.html, the system preference AllowHoldItemTypeSelection had more information for the user to better understand the functionality of this specific system preference. The 18.05/18.11 manual seems to have dropped this information and it would be nice to have it back.
Is this bug still relevant?
I believe it is since this is still an active system preference in Koha and has no documentation related to it in the manual. The system preference is not even mentioned in the 20.05 or 20.11 manual.
Checking between manual 16.11 and 20.11, the AllowHoldItemTypeSelection system preference is explained the same in both. Please check the link to confirm https://koha-community.org/manual/20.11/en/html/opac.html?highlight=allowholditemtypeselection
You are correct- I am not sure why I couldn't find it yesterday! It is there!
