I tried adding placeholder similar to the given for **ContactNumber** for my drop down **Outlet** but it doesn't appear.

Code-

```
<div class="form-group form-icon-group">
    <i class="fa fa-phone" > </i> [tel* ContactNumber /8 class:form-control placeholder "Contact Number *"]
</div>
<div class="form-group form-icon-group">
<i class="fa fa-food" > </i> [select Outlet id:outlet class:form-control "-- Select Outlet--" "Pasir Ris" "Thomson"]
</div>

```

Tried adding `first_as_label "Preferred outlet?"` so this displays as ordinary drop down values.

Rest all of the fields do show the placeholder,any other way to give placeholder for drop down?
