Steps to reproduce:

1. install
2. open https://www.zabbix.com/documentation/7.0/en/manual/web_interface/frontend_sections/dashboards/widgets/gauge
3. open frontend

Result:

Undocumented 'Override host' with not clear and intuitive usage scenario, since what does it mean 'compatible Widget' or 'Dashboard'?

Expected:
Documentation matches the real functionality
