How to make a dropdown filter show details in a table?

[KalebeRS]

Hello,

I have a search for a dropdown filter. My goal is to select one of the Tags and show in which ID's this tag matches.
I'm a bit confused on how can I do that without the duplicates, and how to match this values.

Is there a way?

index= host=  sourcetype=csv source=.........\\resul_test.csv 
| table PR_Tags, PR_ID
| eval PR_Tags=split(PR_Tags,",")
| mvexpand PR_Tags
