With jQuery equalizeBottoms you can “equalize” the bottoms of multiple elements, making columns heights even, even when CSS refuses to help.

Iterates through the cells of a column in a table, it supports colspan but not rowspan. The plugin uses a callback to apply logic to each cell it iterates through.

This jQuery plugin adds a new selector to the selector API for retrieving table cells by their column index. It supports tables with column and row spans transparently, no matter how complex a table is. The syntax for selecting column cells is simple and similar to other jQuery selectors. The selector can take several types of arguments for selecting columns, such as keywords, numeric indexes, and equations.

Transforms a nested unordered list of links (like a Drupal menu, for example) into a Mac OS X-like column view, without requiring changes to markup.

Generates disclosure triangles with Canvas automagically, no other support files required except: Requires Live Query plugin.

Tested with FF3, Safari 3/4, IE 6/7, Chrome.

Update: Now compatible with 1.3.x, without Live Query dependency.

This plugin automatically adds a column with row count. Thus making your tables more readable and keeping your markup/metadata clean.

The use:

With options:

The purpose of this plugin is to provide an alternative to treeview
navigation. Making it look just like the Finder on a Mac is not my
goal, I am after its core functionality. Having said this, I think
that implementing useful features that exist on Mac's Finder (search,
toolback w/ options, etc) is time well spent.

Columnize creates a newspaper-like column layout. The original HTML code only needs small adaptions. In most cases, it is not necessary to adapt the HTML code at all.
Using the plugin is easy:

sets the contents of the DOM node with the ID ›text‹ in a two-column layout with balanced column lengths.

Easily give your site the newspaper layout you've dreamed of, and use Columnizer to layout your content into multiple columns automatically. Resizing the browser will automatically add or remove columns based on available width. Now your layout can automatically adjust to really wide monitors and adapt to narrow iPhone interfaces!

Columns can be sized to fit any width and layout images and complex nested HTML on the fly.

Easy to use:
$('.wide').columnize({width:400});

Advanced options available for more complex layouts.

Column Navigation provides a Mac OS X/NeXTStep style navigation for unordered HTML lists. (Ordered lists will be supported in version 1.1)

It has been designed to progressively enhance list information by refactoring it into columns of data. Each column represents the children of the proceeding selected item.

This is especially useful for formatting long hierarchy structures.
