1) Script Title: Drop down/ Overlapping Content script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...lapcontent.htm

3) Describe problem: I want the "drop down content" to show up, when you click in a table, even when the cell is empty. I thought that it could be done with "onclick".
<td onclick="??"></td>
But I've no idea what to put at the ??.

Can someone help me with this?

Thank you in advance.
