An easy and configurable jQuery expanding textarea plugin that automatically inserts a new row to the textarea when its content exceeds a certain number of characters.

How to use it:

1. Insert the JavaScript textpandable.js after loading the latest jQuery library.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/textpandable.js"></script>

2. Initialize the plugin on the target textarea element and done.

<textarea></textarea>
$(function(){
  $('textarea').textpandable();
});

3. Set the min/max number of rows. -1 means infinity.

$('textarea').textpandable({
  minRows: 1,
  maxRows: -1,
});

4. Set the maximum number of characters allowed in a line. When this limit is exceeded, the plugin will add a new row to the textarea. Default: 20.

$('textarea').textpandable({
  width: 10
});

5. Set the padding & line-height properties of the textarea.

$('textarea').textpandable({
  padding : 1,
  lineHeight: "1.4em",
});

6. Apply a smooth transition to the textarea when expanding & collapsing. Default: 0 (disable).

$('textarea').textpandable({
  speed: 200,
  initSpeed: -1,
});
