Nested is a jQuery plugin which allows you to create multi-column, dynamic grid layouts. Unlike other libraries and jQuery plugins similar to Nested, this is the first script out there that allows you a complete gap-free layout.
It creates a matrix of all elements and creates a multi column grid, similar to other libraries and scripts out there. Then it scans the maxtric for gaps and tries to fill them by reordering the elements. This is exactly how other newer libraries, scripts and modifications behave but if you stop here, the result will sometime leave unwanted gaps as well. That is why there is an option to resize any element at the bottom of the grid that is bigger (or smaller if you prefer) than the gap to make the grid completely gap-free.
