expandable

A jQuery plugin that auto-expands textareas to fit the contents as a user types.

Settings

The expandable plugin has 5 settings:

• duration - The speed of the animation when expanding (or shrinking). Default is 'normal'.
• init - If true, the textarea will be resized to fit its content on initialization.
• interval - The interval at which it checks the textarea. Default is 750.
• within - The number of rows left before expanding. Default is 1.
• by - The number of rows to expand by. Default is 2.
• maxRows - The maximum number of rows the textarea can be expanded to. Default is false which will allow the textarea to keep expanding.

Dynamic Updating

If you need, you can trigger an update to the textarea by doing the following:

$('textarea').trigger('update');

This is useful if you are injecting content into the textarea via JavaScript.
