Ko is undefined in IE9 using select and containerless flow

[jonswaino]

Having difficulty with what appears to be a bug using ko in IE9 with select option bindings and containerless flow:

This works fine in Chrome/FF but not in IE9.
Any help appreciated...

IE doesn't like comments inside select and strips them out. You have two options that I can think of: use a binding on the select that supports optgroup (like #94), or replace foreach with a binding that doesn't require comments (like repeat).

Here's your example updated to use repeat: http://jsfiddle.net/mbest/U7qQZ/3/

ok great, thanks for this. I ended up using the repeat binding.
