There seems to be a bug in the angular bootstrap select demo section. After selecting an option, the dropdown continues to display options instead of hiding them. This issue does not occur when the ng-model attribute is omitted.
You can view an EXAMPLE here.
Here is a snippet of code:
<select toggle selectpicker ng-model="form">
<option>Mustard</option>
<option>Ketchup</option>
<option>Relish</option>
</select>
Best regards,
