jQuery UI Resizable

The jQuery UI Resizable plugin makes selected elements resizable (meaning they have draggable resize handles). You can specify one or more handles as well as min and max width and height.

All callbacks (start,stop,resize) receive two arguments: The original browser event and a prepared ui object. The ui object has the following fields:

ui.helper - a jQuery object containing the helper element
ui.originalPosition - {top, left} before resizing started
ui.originalSize - {width, height} before resizing started
ui.position - {top, left} current position
ui.size - {width, height} current size

If specified as an object, the following keys are supported: { n, e, s, w, ne, se, sw, nw }. The value of any specified should be a jQuery selector matching the child element of the resizable to use as that handle. If the handle is not a child of the resizable, you can pass in the DOMElement or a valid jQuery object directly.

The jQuery UI Resizable plugin uses the jQuery UI CSS Framework to style its look and feel, including colors and background textures. We recommend using the ThemeRoller tool to create and download custom themes that are easy to build and maintain.

If a deeper level of customization is needed, there are widget-specific classes referenced within the ui.resizable.css stylesheet that can be modified. These classes are highlighed in bold below.
