Does Themeroller no longer support ui-checkboxes?

I do开发者_运维知识库wnloaded the latest jQuery UI from their Themeroller site wanting to implement ui-checkboxes and cannot "seem" to find any reference or examples for it any longer.

• Here is an online example of what I was hoping to implement
• This is all I have found to be available (...and I hate this)

Did it go away?

And if so, why?

The version is I downloaded was jquery-ui-1.8.16 (I downloaded the entire thing). I searched all the CSS files with no mention of the tag ui-checkbox.

...it just struck me as odd.

According to that I have found, that particular plugin was broken past the 1.7.2 version of jquery, so it is broken. However, someone did make a version (not sure how compatible it is with the newest versions) that is compatible with 1.8.5. That can be found here

I don't think it's part of the official jquery-ui package. Is it this plugin?
