How to show related data in other drop down if one is selected?

[Neel88]

I have two drop-down on the dashboard. When I select first dropdown from the list then I need the show the selected (filtered) list based on the first drop down on the second. Pls help.

The second dropdown needs to reference the token from the first dropdown.

For a more specific answer, ask a more specific question.  😀

Getting this error after this - Error in 'where' command:Regex:quantifier does not follow a repeatable item

| loadjob savedsearch="nobody:splunk_fcr_evo:monitoring"
| table adt, FLOW, Date, NbRecordsOKFCR, Total, NbRecords, NBFile, NA1, NA2, NA3, CM, Alert
| where match(FLOW, "$Flow_token$") and match(adt, "$adt_token$") $filter_green_lights$
| fields adt FLOW Date NA1, NA2, NA3,CM, "Total" | sort adt, Date

What are the values of the $Flow_token$ and $adt_token$ tokens?  One or both is using a quantifier ('*', '+', or {n}) incorrectly.  Those tokens must contain a valid regular expression (test them at https://regex101.com).
