I have filled a LIST/MENU with dynamic content.
The value of an <option> is a number (id)...
How can I read out which item is selected when the form is submitted?
I assume you're not using anything server side to get the value since this is posted in the client side forum?
You could use an onSubmit event handler in your form tag to call a function and get the menu's value, performing an action depending on what option was selected.
