I have tried changing the color of md-select
underline with the following css:
md-input-container > md-select {
border-color: rgba(13, 148, 74, 0.82);
}
but it doesn't work.
Here is the html which contains the md-select which I want to customize:
<md-input-container>
<label>Items</label>
<md-select ng-model="selectedItem" md-selected-text="getSelectedText()" ng-required="true">
<md-optgroup label="items">
<md-option ng-value="item" ng-repeat="item in items">{{item}}</md-option>
</md-optgroup>
</md-select>
</md-input-container>
