Open modal window with extern URL?

Hello,

how can I open a modal window with a external url?

e.g. I want to open Google, but WD Code should stop and the google window is in front of my portal until it is closed. Then WD code continues.

WDPortalNavigation.navigateAbsolute(..) can't open a modal window, right? WD Source Code keeps running...

Can I open a WD-Window with context from a external URL?

I would be grateful for any help!

Best regards
