"quickset" is the ability to add custom configuration property to a class.
You can write eg. "verticalScrollerType" in the search box in the config panel. if "verticalScrollerType" is a property managed by architect you can setup your value.
If you have no results means actually Architect can only add it as a custom property, you must click "Add" and then choose a type of property (Array, Boolean, Number) with a click on the icon on the left of your new "verticalScrollerType" config option.
Here is a helpful note for others if they come across this in the future.
Be sure the store's response totalProperty is populated with the count of the entire record set and not just the count of the returned subset. It won't scroll without the ability to calculate how many pages in total are in the complete record set.
ie. If total record set is 10000 records, totalProperty = 10000 not 200 returned in the paged data set.
That's the way I am doing it, but I'm not fond of the idea of always having to do a count even when paging with no criteria change. I will probably play with the idea of having a separate AJAX call for the count that only gets called when criteria is changed. While the count in my prototype only takes 0.052 seconds, if I can only have that once every 10 requests, the total time is much smaller and should scale better.
This is all assuming the ability to populate the total count separate from the response of the paging requests.
