SmartMarkUP – Universal Markup Editor and Platform

SmartMarkUP is a lightweight and powerful JavaScript library that allows you to turn any textarea into a fancy markup editor. HTML, CSS, XML, Wiki syntax, BBCode or any other desired markup language can be implemented and/or adjusted to your preferences and business needs. SmartMarkUP doesn’t depend on any other JavaScript library and can be integrated with any already existing JavaScript library or code.

With single line of code you can turn any general textarea to powerful markup editor. As far as integration is unobtrusive, HTML of your application will remain unchanged. SmartMarkUP degrades gracefully for users without JavaScript without loosing functionality of your application.

SmartMarkUP is completely customizable and scriptable as well. Changing styles, implementing new markups, creating extra buttons and submenus or adding new functionality is a matter of minutes. SmartMarkUP is distributed under GPL open source licenses, so SmartMarkUP is absolutely free and you can do anything you like with it!
