Navbar dropdown menu hidden behind embed tag in IE

[ghost]

The menu items of a bootstrap navbar (v3.3.2) are shown behind the embed tag that I'm using to display various contents (pdf in my case). What happens is that when i click on a menu list item, in internet explorer it goes behind the embed, while in chrome or firefox it opens above (that's the correct behaviour).

This is the code used:
