This demo illustrates two composite panels, each with a set of adjusters that are dependent on another boolean adjuster.
Initially*, you should see only a single on/off switch in each panel. Turning the preference on should reveal the dependent adjusters, and turning the preference off should hide them.
Any values set with the dependent adjusters should be preserved even if the controlling preference is turned off.
* Once the page is loaded, preference values are stored in a cookie, so on subsequent page loads the stored values will be used. To reset the demo to its default state, clear cookies for the page.
