Several years ago the legendary Gregor posted some nice demos of javascript hacks and one of them achieved just this. Actually, it utilized CSS {pointer-events: none} by calling it through javascript injection. It tells the browser to essentially ignore a widget as if it were not there, thus passing events (like OnClick) to widgets underneath it. It was originally done in RP7, updated for RP8, but should still work (hopefully) in RP9. I can’t find the threads in the forum and they would probably be archived by now anyway.
Here is the RP8 library, which you can import to your Axure editor:
AxureJS 8.01.rplib (280.2 KB)
Here is a demo of it in action, see the “Pass Event” page:
JSLibraryExamples.rp (82.4 KB)
To use it, just drag the “Pass Event” from the library (or cut & paste from the .rp file above) onto a page and edit the “myWidget” text with the name of your dynamic panel (or whatever widget you want to be “non-clickable”). The Pass Event widget will hide itself on page load.
