jQuery UI 1.9 Milestone 8 – Position

Posted on by

The eighth milestone release for jQuery UI 1.9 is out. There are quite a few improvements and changes since the last milestone release. Most notably, the Position utility redesign is done.

What’s a Milestone Release?

A milestone release makes it easier to try out the latest development code of jQuery UI without necessarily having to check out code from GitHub.

With a milestone release you can try out new widgets that are pretty far along (though not yet final) and provide feedback based on released code with a specific version number.


The Position redesign is now fully implemented. The using option now provides information about where the element is relative to the target. This information is useful for a variety of reasons, such as knowing where to render an arrow if you want the element to point to the target (think of tooltip with callouts). This information is passed in a second parameter to the using callback.


The Tooltip and Autocomplete widgets have been updated for full ARIA support. Getting these widgets to be fully accessible with various browsers and assistive technology was quite difficult. A huge thanks goes out to Hans Hillen and Everett Zufelt for their help with testing and implementation.

A ton of bug fixes

A lot of components have seen a lot of bug fixes. While we continue to maintain the 1.8 branch, a lot of bugs get only fixed in master. Here are all tickets fixed in 1.9, by component.


You can download the jQuery UI 1.9 Milestone 8 – Position release as a zip file or via git:
