We're aware of Javascript scripts that can genearate the require HTML5 elements (so IE can actually st...

For example: I recruit two...

Currently I sort R by y then x...

I was struggling with nested sets, specifically building one on the iPhone using sqlite. I found a handy script that I then adapted from PHP. It basically sets the left and right values based on parent ids. So you need a table where each entry has an 'id' and a 'pid' as well as 'lft' and 'rgt'. I find it easy to map the ids to their re...
