How to automate default values to populate in a panel when the dashboard is opened?

[yvassilyeva]

I have a link list with three tabs (A, B, and C). When A is clicked three panels open (X, Y, and Z) and one drill-down (that doesn't show values unless one of the panels (X, Y, or Z) is clicked on).

How do I get the drilldown to automatically be filled with values for the X panel?

So, it would be: When A is clicked, I have X, Y, Z, and drilldown, with X values open at the same time.

Very appreciated! Thank you.

You can always have a token initialized when the dashboard opens.

Check out this doc for setting tokens on page load using <init>
