jQuery UI 1.9 Milestone 4 – Accordion Redesign

Posted on by

The fourth milestone release for jQuery UI 1.9 is out, featuring the updated Accordion widget. This release also includes updates and bug fixes to existing and new widgets that will not make it into a 1.8.x release.

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.

Note: the API is subject to change as the code is still under active development.


The Accordion API has been redesigned for simplicity, extensibility and consistency with other widgets in jQuery UI. We’d love to get feedback on any compatibility issues you may have with existing code. Everything supported in 1.8 should work out-of-the-box in 1.9; if something breaks, we will work to fix it before the final release.


As mentioned above, 1.9 will support the 1.8 API, as well as the redesigned API. However, this introduces two problems. First, some of the APIs don’t overlap cleanly. For example, in 1.8 you can collapse an accordion by setting the active option to false or -1; but with the API updates, you can set the active option to a negative number in order to activate a panel starting from the last panel instead of the first (similar to .eq()). Second, while both APIs are supported, it’s hard to test whether you’ve successfully updated all of your code for compatibility with the 2.0 release which will not support the 1.8 API. In order to deal with these issues, we’ve introduced a flag, jQuery.uiBackCompat, which can be used to prevent the backward compatibility layer from executing. This flag must be set after jQuery is loaded, but before jQuery UI is loaded. Toggling the flag after jQuery UI has been loaded will have no effect.


You can download the jQuery UI 1.9 Milestone 4 – Accordion Redesign release as a zip file or via git:

To help with the testing of the Accordion redesign, visit the Accordion page on our Development & Planning wiki.


If the comments section on the wiki page doesn’t provide enough room for your feedback, post to the Developing jQuery UI Forum and tag the post:

How to Contribute Code

If you have code changes for the Accordion, fork jQuery UI on GitHub and submit a pull request.

If you’re new to git or GitHub, see our guide: How to submit a fix to jQuery UI – The Easy Way.


Note: please do NOT use the comments section of this blog post for feedback on the Accordion widget. This discussion should occur on the wiki page and the forum (see How to Provide Feedback, above).

Unleash The Grid

Posted on by

The jQuery UI Team is proud to announce that we are building a rich, fast grid widget that will enhance an HTML table with data linking, sorting, paging, filtering, row selection, and inline editing. As part of this process, we’ll be building the features of the grid as standalone widgets and revisiting existing jQuery UI components. At the end of this process, not only will we have a grid, but also a better-tested, more feature-complete user interface library.

Current Progress

We are nearing completion of development on Stage 1 of the project, which encompasses the creation of a generic data model, data type parsing, and markup. This stage will culminate in a “zero feature grid,” an enhanced HTML table that supports the jQuery UI CSS Framework and serves as a base for other grid features. See the roadmap for details on work planned for future stages.

Development Approach

There are already a number of high quality jQuery grid plugins. We recognize they each have an impressive set of features, capabilities, and a level of use by members of the jQuery community. We are studying and applying practices and techniques from today’s most popular grid and data table plugins, including current favorites, SlickGrid, jqGrid, DataTables and a few that have not been updated in a while, like Tablesorter, Flexigrid, and Ingrid. We invite all authors and users of these and any other grid plugins to get involved in the design of the jQuery UI Grid.

Not Invented Here?

As you may imagine, we’re pretty big fans of the jQuery UI API. We believe that having a consistent interface to complex plugins is a big win for users. Sometimes in the past, we’ve adapted already-complete plugins. Unfortunately, this approach can lead to headaches related to legacy bugs, inconsistencies with the rest of our API, and lack of familiarity with the original design decisions. By building from the ground up, we can ensure that each line of code has been vetted and that any grid we call “jQuery UI’s” conforms to our standards.

More Than Just A Grid

We’re not just developing a grid, but rather designing and building modular and extensible components, like sorting, paging, filtering, and in-place editing, that can be combined into a grid. We’re confident that jQuery UI users will find compelling and creative uses for the new suite of tools that are being built to support the grid.

Refactoring Interactions

While jQuery UI’s mouse interaction plugins work well enough in many cases, we are well aware that they have lingering shortcomings – including their ability to work properly on tables. As part of the Grid development, we’ll be giving the interaction plugins a long-awaited refactoring to simplify their APIs, address edge cases, and generally ensure their suitability for a wider variety of contexts.
