Allow viewing event details in Live Activity view #42730
Description
Feature request
Is your feature request related to a problem?
Yes. In the Live Activity view, I cannot click on an event row to expand it and see its properties. To inspect event details, I have to switch to the "PostHog default" view, find the event again, and then expand it there. This breaks the debugging workflow when monitoring real-time events.
Describe the solution you'd like
Allow clicking on an event row in the Live Activity view to expand it inline, showing properties, metadata, and raw JSON - the same way it works in the other Activity views (PostHog default, Project default).
Alternatively, the ... menu on each row could include a "View details" option that opens the expanded view in a side panel without leaving the Live view.
Describe alternatives you've considered
- Switching to "PostHog default" view to find and expand events (current workaround, but loses the live feed)
- Copying the event ID and searching for it (tedious)
Additional context
The Live view is great for real-time monitoring, but the inability to quickly inspect event properties makes debugging slower than it needs to be.
