Browsing templates was easier when popup displayed all template host groups, not only sub-groups.
Steps to reproduce:
- Navigate to Configuration -> Actions -> Autoregistration actions
- Press "Create action" and switch to "Operations" tab.
- Click on "Add" button and choose "Link to template" operation type.
- Open multiselect popup.
You cannot browse all templates in "Templates" host group. Only sub-groups are available in Host group selector.
Before Zabbix 5.0 there was also "Templates" host group available so user was able to see all available host groups.
