Factory boasts a number of other features as well… plenty of headers and header badges, various menu styles, background choices and so much more. Head over to Elixir Graphics and have a peek at his latest hi-tech creation.

ExtraContent was first introduced in December of 2008 and since then dozens upon dozens of themes have cropped up using the technology. Here are just a few that have come out in recent months.

Henk has become a veritable champion of ExtraContent, pushing the limits of the his themes and the technology with release after release of ExtraContent enabled themes. Exposure has 3 EC areas, on the header above the title/slogan, between the content and the footer and below the footer. Exposure has a jquery fading dropdownmenu. Down- and Right-Arrows show the menu-items with sublevels for clear navigation through your website. When opening a page the menu slides down with a fading effect. You can disable the sliding in the Theme Styles.

Say hello to Mirage, a new RapidWeaver theme that raises the bar yet again, making it even easier to design the site that YOU want to create.

Tired of rigid limits and cookie-cutter themes? Then you’ll love Mirage – a design experience that frees you to build a site that can both fit the mold, and break out of it.

Ever thought it would be great if you could just choose where the header image goes? Mirage can do that. But what if you want the logo and title of your site above the menu, and the header image below it? Mirage can do that too. Don’t like header images? Want to add your own custom image to the background of the theme? Maybe stretch the menu the full width of the page? Mirage can do all that, and much, much more….

Every once in a while, something comes along that really stirs things up. That’s what the iPhone did to the mobile industry, and in that same spirit we figure it’s time to set a new standard for RapidWeaver themes everywhere.

Introducing Phelix, a new theme that puts you in complete control of its exquisite design. And offers near flawless Internet Explorer 6/7/8 support (minus drop shadows and rounded corners). And automagically creates a completely customized version of your site for iPhone, iPod Touch, and Android devices. And includes built-in support for FancyZoom, CrossSlide, and Pulse.

Henk has been a big advocate for ExtraContent themes and has managed to add ExtraContent in just about every theme he has released in the last 6 months. STALKER, Henk’s latest RapidWeaver theme, has 4 ExtraContent areas that allow the user to add more content then RapidWeaver typically allows — EC1, above the Menu. You can use this area for some textlines or your logo. With a CSS code you can fill this area with any image cor colour — EC2, below the Menu. This area floats together with the menu and can be filled with text, images or a logo. — EC3, above the Footer. — EC4, below the Footer.

Will Woodgate from ThemeFlood takes what I believe is his first foray into ExtraContent theme development with his latest theme, NewsMedia. Will has taken the ExtraContent concept to the extreme with up to 15 possible ExtraContent areas in NewsMedia.

Will doesn’t stop there, mind you, as NewsMedia is packed with professional features like style switchers, mega-menus and horizontal scrolling menu bars.

And last but not least, old RapidWeaver theme star, MultiThemes is back in the game with Panels Pro, a theme that makes use of 2 ExtraContent areas. True to MultiThemes form, this theme is high and style and lush with all the finishing touches. Like a fine Italian automobile, MultiThemes leaves no corner unpolished.

Check out Panels Pro.

Imagine

Imagine from WeaverThemes is a highly polished and styled to perfection RapidWeaver theme that employs a sexy bit of javascript animation to tuck away and hide one of it’s ExtraContent areas in a drop down panel at the top of the screen — very cool. Imagine also has an ExtraContent area below the main content.

Slider

RWT’s Slider takes another innovative approach to ExtraContent in the form of a sliding banner. We’ve all seen them before but propagating them with content has always been a hassle. RWT has taken the ugly out of coding a sliding banner and made it ExtraContent easy. It can now be as simple as adding text to any page or sidebar that allows for styled content.

One other thing that sets Sleeker apart is the split-hybrid navigation system that allows nested pages to be displayed both in a tidy drop down and in a vertical sidebar format. For more information, check out Sleeker Ultimate.

TW009 makes use of two EC areas, a pre-content and post content area that are visually separate from the main body of content but sharing the same design characteristics.

Another unique feature of TW009 is it’s header which can display up to 5 header images at once. Very cool. Check out the new and improved TW009.

Some other notable enhancements are panel height adjustment, panel hiding options, full font control and complete color control. Go take a look at the new and improved TW002.

You can check out the new H3 here, and take a look at the tutorial movies. Take an especially close look at this movie, which demonstrates how you can use ExtraContent to make a search bar in your sites header.
