Steps to reproduce:

1. Go to https://www.zabbix.com/documentation/current/manual/api/reference/item/object check the flag description

Result:
Missing description of all flags possible values
Expected:
More details, for instance:

0. Normal items (ex: Zabbix ping)
1. Items used for the discovery (ex: *Disk Discovery*)
2. Items in discover (ex: *FS {#FSNAME} used disk space*)
3. Undefined
4. Discovered items (ex: *FS [/sda] used disk space*)

 

(Do there is a better way to suggest modification of documentation ?)
