Is there an editor that can build web based UIs using a JavaScript framework like jQuery (jQueryUI)? The desirable editor should allow me to do page layouts and templates. Then I should be able to organize my content and forms and apply requisite CSS and of course this should be cross browser.
I have checked Sencha Architect http://www.sencha.com/products/architect/ that uses the ExtJS framework but it falls well short of my expectations and of course it honors only ExtJs.
