Extends the rendering pipeline to enhance a component with other features (mixins).
Extend components with features
<custom-formis="validatable">Features are just components, and will be invoked on the element during a render in the same way as the base component. The base component will be invoked first and then any features specified (you can specify multiple features).
ripple('base-component',function(){this.innerHTML='foo'})ripple('feature',function(){this.innerHTML+='bar'})<base-componentis="feature">foobar<base-component>This pattern is the same as:
d3.select(element).call(component).call(feature1).call(feature2).call(feature3)Features may also contribute and mixin their own styles (just extend css attribute).
