There are several ways to do drilldowns in Splunk, but to highlight the value of the clicked field (which is how your question sounds to me), set the following using the Drilldown Editor:
Change the "On Click" action
Choose the right App & Dashboard name. Under Advanced, set the target Dashboard’s token(s) to the relevant value(s) from your starting point. Note the potions to select various elements from the starting panel on your dashboard. In your specific case, you’ll want to assign $click.value2$ to a target token. You may also need to pass other values (either tokens you’ve created, or inbuilt ones from Splunk). For every additional (or hard-coded value) you need to pass to the target, click the "➕Add New", and repeat the process.
Here’s an example final format (be sure to use the correct target and source token names)
