I had problem with aligning my horizontal drop down menu to right side of `row` container. It is because I have `position:fixed` in my css but it is only way to style this type of menu.

Here is my css:

```
.top-main .dropdown-menu {
  width: 100%;
  position: fixed;
  top: 87px;
  z-index: 1000;
  text-align: right;
  padding: 5px 0;
  margin: 0 auto;
}

```

And whole menu you can see here: <http://www.bootply.com/mNP0ficFef>

As you can see the menu is aligned to right side of monitor, but it should be aligned to right side of `row`. Any suggestions?
