Sadly that didn't work, but to be honest I didn't think it would, as the dynamic drop downs are created using an onChange event. When you select the first one it populates the second, and when you select the second it populates the third, and so on.
There are 4 dynamic drop downs in total, but not all are shown, it depends on the data selected. Most of the time its just the first 2, but in rare occasions its all 4.
The dynamic drop downs filter a recordset, but I want to be able to change the filter once the data is shown, so I need the dynamic drop downs to repopulate on page load, is this possible with this extension?
