Hello,

Since Zabbix 5.2, screens have been replaced by hosts dashboards. A screen was displaying all graphs from a graph prototype on one page whereas hosts prototype only display a selected number of graphs over multiple pages. Problem: when there are no graph to display, Zabbix shows empty placeholders.

Step to reproduce:

1. host template with a dashboard
2. a widget to display graphs from a graph prototype (mounted filesystems for example)
3. configure 1 column and n rows of graph
4. display the host dashboard of a host with n+1 discovered items and go to the last page

Expected behavior: Zabbix shows one last graph

Current behavior: Zabbix show one graph and n-1 empty areas

See screenshots attached with 4 rows of graphs.

Solution : don't display empty <div> if there are no graphs to display or bring back the "screen" behavior where every graphs where displayed (no pagination)
