Hi,

In the drop-down filter, I want to reference the ts field value from the timestamp filter. How to do this?

Thanks,

</div>

can you show full expressions for both controls ?

something like this should work:

timefilter:

`timeFilterControl column=@timestamp compact=true filterGroup="timeGroup"`

dropdown filter:

`kibana | selectFilter group="timeGroup" | essql "select userMail from "mytable" | ...`
