MooTools 1.3 only!
DynamicTextarea is a reusable class that can by applied to any textarea tag on a page (with any sort of CSS styling attached to it) that allows it to dynamically resize based on the content it contains.
Constructor:
new DynamicTextarea(el,options);
//el: A dom node or id string.
//options: an object containing key:value pairs for configuring the class. Check the source for more details on available options
In Context:
new DynamicTextarea('myInput',{
minRows:2
});
This will ensure the textarea is always at least 2 rows tall.
Opera fails with certain CSS styles, so please test Opera and disable if necessary.
