Description:

Enables offsets to be used to hide elements in the source screen that you don't want to be viewed in the FileMaker Web Viewer - this is an amazingly useful function enabling you to precisely control what information - for example from a mapping site - you choose to display.
This updated version also resizes the source content as the web viewer is resized as the Filemaker Window is resized.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discovered a very interesting affect of this. If you have a negative offset, then clicking in the webviewer window produces a click in the associated region of the Filemaker layout.

So by scrolling in a web viewer, I select and scroll text in a field that is above and to the left of the web viewer. Very weird.
