autoGrow jQuery plugin

Auto resize input fields to fit content when user types.

Works both with jQuery and Zepto.js.

Usage

To autoresize text field use:

$('#myTextField').autoGrow({
  comfortZone: 70 // default value
});
// or just
$('#myTextField').autoGrow(70);

When you update styles that change text size use:

$('#myTextField').autoGrow();

You can also update comfort zone:

$('#myTextField').autoGrow(newComfortZone);

To disable autogrowing:

$('#myTextField').autoGrow('remove');
// or
$('#myTextField').autoGrow(false);
// or
$('#myTextField').autoGrow({remove: true});

Limiting width

To limit width use css properties min-width and max-width. When min-width is set to 0px (default browser value), minimum width is limited to current width.

Animating

If you wish smoothly resize textfields use following styles:

#myTextField {
  transition: width 100ms linear;
}

Do not forget to add vendor prefixes for transition.
