More details please. What exactly do you want to have happen?

For example, do you want the selection from the menu to immediately retrieve a specific page, or is this menu selection to take effect when the form is submitted?

If the latter, what do you want to have happen if the form is invalid?

Any other details or context around this that you can supply would be helpful.
