Is there a simple open source javascript website builder that I can use in other projects? jQuery UI is a really good starting point, but I wonder if there's anything that took it further. I'm looking for:
- simple building blocks (text, headings, bold, italic and images)
- grid based drag & drop
- nice UI or themable
- can read initial positions from a configuration file (so I don't have to generate javascript code from php)
- use same code to display the page on the front-end?
