ngSelected
ng
The HTML specification does not require browsers to preserve the values of boolean attributes
such as selected. (Their presence means true and their absence means false.)
If we put an Angular interpolation expression into such an attribute then the
binding information would be lost when the browser removes the attribute.
The ngSelected
directive solves this problem for the selected
atttribute.
This complementary directive is not removed by the browser and so provides
a permanent reliable place to store the binding information.
<OPTION ng-selected="{expression}"> ... </OPTION>
