If you are a WordPress Theme designer, with WordPress Themes already released or on the way, and you would like to add the new WordPress Widgets to your Theme, read Widgetizing Themes from Automattic – WordPress Widgets.
This page contains technical instructions on updating a theme for use with widgets. Many themes can be updated in five to ten minutes. Others will take an hour or two to get all of the kinks worked out. Some will look awful no matter what you do. This document assumes basic PHP editing skills, though you probably won’t have to write any code of your own.
In summary, WordPress Widgets Wilt WordPress Wizards.
These can be very easy to use and very complicated. Take your time. Read through the instructions carefully. And seriously consider if your WordPress Theme really needs these. Some do, some might not. It’s up to you. WordPress accessorizing Widgets are just one more tool in your WordPress Theme design arsenal.
And remember, it turns over part of the design elements to the user, so take this into consideration as you plan or renovate your WordPress Theme.
Also, the WordPress Support Forum volunteers are just getting up to speed on these new widget gadget toys. They might not have the answers you need. Begin with the step-by-step widgetizing instructions and look around the web for more answers before hitting the forums. Then search the forums thoroughly before asking, since you are probably not the first to ask.
For users having trouble with WordPress Themes using WordPress Widgets, contact the Theme author first as the problem is with the Theme. If this fails, then turn to the Forums for help.
WordPress.com bloggers should use the WordPress.com Support Forums and the Feedback button from the Administration Panels for help, not the WordPress Support Forums.
