The HTML5 Fun Pack for NetBeans IDE, first announced in part 1 of this series, is now updated to include HTML5 code snippets for drag & drop, range, color, and e-mail. Click to enlarge the image below and notice the HTML5 Palette in the Component Palette on the right of the screenshot:
All the tags and code from line 10 to line 32 above magically appear when you drag and drop the 'Range' palette item into the HTML editor. Similarly, the other palette items typically provide more than a simple HTML5 element, i.e., related JavaScript, where applicable is included, so that you have a complete context for getting started working with a specific feature that is new in HTML5.

Why I do not see the HTML5 panel when open file with extension .php?
Because that's not supported at this stage. I'll take a look into it.
