Zabbix disabled items


I have setup grafana with zabbix plugin. It worked well. I can see the hosts registered in the zabbix.
I am trying to create a dashboard for a custom item created in zabbix. This custom item is working fine
and yielding metrics in zabbix. But I can see the item in grafana only when clicking the “show disabled items” button. When I select it, i dont see any data coming into the grafana. So how do I enable the disabled items from zabbix in grafana ?
