- /*
- * Sub class that adds a check box in front of the tree item icon
- *
- * Created by Erik Arvidsson (http://webfx.eae.net/contact.html#erik)
- *
- * Disclaimer: This is not any official WebFX component. It was created due to
- * demand and is just a quick and dirty implementation. If you are
- * interested in this functionality the contact us
- * http://webfx.eae.net/contact.html
- *
- * Notice that you'll need to add a css rule the sets the size of the input box.
- * Something like this will do fairly good in both Moz and IE
- *
- * input.tree-check-box {
- * width: auto;
- * margin: 0;
- * padding: 0;
- * height: 14px;
- * vertical-align: middle;
- * }
