13 | This DHTML & Drag&Drop Library adds Drag&Drop functionality |
---|
14 | to the following types of html-elements: |
---|
15 | - images, even if not positioned via layers, |
---|
16 | nor via stylesheets or any other kind of "hard-coding" |
---|
17 | - relatively and absolutely positioned layers (DIV elements). |
---|
18 | Moreover, it provides extended DHTML abilities. |
