The requirement is to display a panel only if the user clicks on a specific column in a previous panel. Kindly help.
@varun99 usually more details of what you currently have and what you have tried would help us assist you better. You can definitely use the examples from Splunk Dashboard Examples App which has examples to set token based on table where any value for specific field is clicked. It also has example for showing and/or hiding panel depending on depends/rejects attributes.
Following is a run anywhere dashboard example based on Splunk's _internal index which sets specific token depending on clicked field name and shows/hide panel using depends attribute.
