That sort of functionality is quite involved. The descriptions below are for Simple XML https://docs.splunk.com/Documentation/Splunk/latest/Viz/PanelreferenceforSimplifiedXML https://docs.splunk.com/Documentation/Splunk/9.1.1/Viz/tokens https://docs.splunk.com/Documentation/Splunk/9.1.1/SearchReference/Collect In your dashboard you will need something like <drilldown>
<set token="clicked_url">$row.URL$</set>
<set token="run_collect"></set>
</drilldown> You will need a global search that does the collect, e.g. something like this will create a new row with your user/URL and collect that to your index. This search is dependent on the run_collect token being set, so will only happen when the user clicks the row. It will unset the token at the end, so it can run again. <search depends="$run_collect$">
<query>
| makeresults
| eval user=$env:user|s$
| eval URL=$clicked_url|s$
| collect index=your_index
</query>
<done>
<unset token="run_collect">
</done>
</search> As to hiding the data on the dashboard, is this to be hidden forever or just in this version of the dashboard? Much will depend on that. You don't actually need to collect it to an index, you could write this information to a CSV lookup, which may be a better option if you want to hide this information all the time once clicked. In that case you could use that as a lookup to filter previous clicked information. Anyway, this is a fairly complex use case for a dashboard - it's certainly all possible, but this is a bit more involved for a basic dashboard. This is NOT applicable to dashboard studio - you mention both in your question tags. In principle the approach could be the same, but the technical implementation is not as above.
