Portal Page with IDA object

I'm trying to understand how this works. (never did an IDA object before on a Portal Page).

I created a new portal page. Added an IDA object. Changed the drill mode = select. Built the API for HR01.1. Selected the Drill Around Path = Process Level (H03). Added my company in the Drill Key.

When I run it, it seems to work ok. It displays a list of all my Process Levels. It has the Find Options on the left side where I can find and filter. etc. The first record has a little "right pointing triangle" with the record hilited in blue.

The problem is it won't let me "select" or click any other row. So how or what would allow me to select a row?

I also noticed when in the Script window and I choose ida0 for the object, the only two events are OnLoadBegin and OnLoadComplete. So how would you know if they did click on row 3, what the value of the row elements are?
