问题
I have a jQuery modal dialog in which I am rendering a datatable. I am required to use the ColVis plugin in order to dynamically show or hide columns of this datatable. The problem is that when I click on the Show/Hide Columns button, the column list does not render on the modal dialog. It renders behind it! I have to close the dialog in order to see this list.
The same thing when implemented in a normal page(without a modal dialog) works absolutely fine. Any idea how to fix this modal dialog problem?
