I have a drpdown list. In my html I have this:
<select id="universitySel" ng-model="universityValue" ng-options="university._id for university in universities">
<option value="-1">Choose university</option>
</select>
I bind this dropdown from my collection. I want to show optional text as first element as you see above. First element is always empty. How do I do this?
Set the value to an empty string "":
<option value="">Choose university</option>
(from Angular's documentation:)
Optionally, a single hard-coded
<option>element, with the value set to an empty string, can be nested into the element. This element will then represent the null or "not selected" option.
