Switched everything over to use Typeahead.js and Bloodhound.js. Tried to keep proper formatting intact, but a second look would be appreciated. Will post screenshots as well. 
You can nest Sass like this:

```scss
.left-inner-addon {
  position: relative;
  
  input {
    // ...
  }

  i {
    // ...
  }
}
```

... which is equivalent to what you have above.
