I have an MVC page, with some controls inside a form. The part I need help with:
I have a bunch of dropdowns in a list. All dynamically named (drop{0}, where {0} is the id 
(really, its just a counter: 1,2,3,etc)). At the top of the list, I want to have another dropdown that will update ALL the dropdowns when it is changed. I've done similar things with checkboxes (check one and all are checked, etc) so I assume this can be done, hopefully just as simple. I'd prefer it to be on the client side, so once the form is submitted, the new values will be added/updated to the database.

Edit: The values of ALL the dropdowns are static. They are all a list of 1-50, representing the number of cards I need to produce for a given record.

This is how I did the checkbox:

```
$("#chkSelectAll").click(function() {
      $(".checkbox").attr('checked', this.checked);
 });

```

Any thoughts on where to begin?

Thanks!
