Hi there,
this is quite simple to do here is a code snippet:
<h3>Select binary point:</h3>
<div layout="row">
<md-input-container flex>
<label>Choose a point</label>
<ma-point-list limit="200" ng-model="myPoint"></ma-point-list>
</md-input-container>
</div>
<p>
Point Value: <ma-point-value point="myPoint"></ma-point-value>
</p>
<p ng-hide="myPoint.value">
Watch me hide
</p>
or to hide when false:
<p ng-hide="!myPoint.value">
Watch me hide
</p>
or
<p ng-show="myPoint.value">
Watch me hide
</p>
