This would list numbers `5.0` to `7.0` in a drop select menu:

```
<%= f.select :height, (5..7).step(0.1) %>

```

How would I list `5.0` to `7.0` but also include an option of "Below 5.0" and "Above 7.0" as part of the menu?

I'm trying to create a dropdown/select menu for my users to select their height and wish to avoid doing it the long way.
