Grafana dropdown tiles not Showing on Dashboard

[shashaagl]

• What Grafana version and what operating system are you using?

• Grafana v8.1.3 (a61f38238c)

• What are you trying to achieve?
  Creating a dashboard by sourcing the data from Graphite. The data is being fed into Graphite by using lighthouse reports which I want to be shown into Grafana dashboard

• How are you trying to achieve it?
  Sending the data to Graphite using below command and I am able to integrate this with my Grafana and also can see the data in the dashboard

lighthouse-graphite https://www.mywebsite.com/help --run=3 --graphite-host=mygraphitehost --graphite-prefix=lighthouse.mywebsite_com

• What happened?
  I can see the data being generated into Grafana but the dropdown panels are not visible. I have 3 different websites with multiple pages and I want to show all of them in Grafana. User should be able to select the domain/url/page from the dropdown and accordingly data should populate

• What did you expect to happen?

• Can you copy/paste the configuration(s) that you are having problems with?

• Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.

• Did you follow any online instructions? If so, what is the URL?

Have you created variables for your dashboard?

Add and manage variables | Grafana documentation

Once you have created the variables, they then have to be used in the queries. You can see some example dashboards for graphite on the play site:

https://play.grafana.org/d/cvDFGseGz/graphite-templated-nested?orgId=1

This is the app variable - the edit mode in the dashboard settings:

And this is the variable being used in a Graphite query - the $app variable is substituted for the value from the dropdown when the query is executed:
