Hi,

I have in Elastic the below data:  
 ![image](https://us1.discourse-cdn.com/elastic/original/3X/e/1/e149ed450f7a91458d542f1dcc43ac3e403a6a2b.png)

I also made the below graph :

 ![Graph](https://us1.discourse-cdn.com/elastic/original/3X/b/8/b8cd594eb8f36ba13b9a407f17a0d136b8fb22dc.png)

Vnf z1 has as counters MemUsed & CpuUsed, whereas vnf z2 has as counters CpuUsed & MaxCpuUsed.

If I filter the above graph with "vnf\_name is z1" and after that I want to filter with a specific counter, could it be possible only MemUsed & CpuUsed to be shown in the drop down menu of counter\_name.keyword ?

Thank you in advance! 🙂

Hey @Voula_Mikr!

You can do this using the [Parent control option](https://www.elastic.co/guide/en/kibana/current/add-input-controls.html#_dropdown_menu).

1. Create an `option list` control panel for your `vnf_name.keyword` field
2. Click the Add button to add another `option list` control panel, this time choosing the `counter_name.keyword` field and then selecting the `vnf_name.keyword` field in the Parent control box.
