Hi -- I've succeeded in disabling an HTML button (greying out and inactivating) by:
- setting HTML button's button attribute to: id="myButton"
- creating a conditional HTML region that, when rendered, disables the button using
source of: document.getElementById("myButton").disabled = true;

I need to do something similar for either an entire region (eg all its contents) or just a list (which happens to be the only item in this particular region).

In the following example, I'm trying to disable the region:
I have a region of type LIST: Table List which contains the list in question. Its Table Cell Attributes are set to: id="tableCell". (This is a complete shot in the dark; didn't really know what the purpose of this attribute was when I was attempting this...)

I also have a region of type HTML Text, no Template, display before footer, which, similar to button example above, is conditional and its source is: document.getElementById("tableCell").disabled = true. The conditional disabling doesn't work and I get no errors.

1. How can I accomplish disabling a region or list?
2. For the heck of it, I changed my list region's type to HTML Text, to see if this would help. The included list went away and now I can't change the type back to: LIST: Table List. HELP?
3. In these regions that control display, the HTML source is being displayed when the region renders. How can I prevent this? (More pertinent for the button disable, as this is actually working.)

Thanks much!
