Auto Multiple Columns With MooColumns
MooColumns is a Mootools class that helps creating multiple-column contents easier & quicker.
It automatically divides the contents into columns and supports multiple instances to be run at the same page.
MooColumns is highly configurable. You can mention the classes which the column-creation will be applied, specify column-break elements, number of columns & column widths. Or leave all these settings to the default ones.
This Mootools class is currently in beta but looks promising and very functional for presenting the content.
