@polymer/paper-behaviors v3.0.1

<paper-behaviors>

<paper-behaviors> is a set of behaviours to help implement Material Design elements:

• PaperCheckedElementBehavior to implement a custom element that has a checked property similar to IronCheckedElementBehavior and is compatible with having a ripple effect.
• PaperInkyFocusBehavior implements a ripple when the element has keyboard focus.
• PaperRippleBehavior dynamically implements a ripple when the element has focus via pointer or keyboard. This behavior is intended to be used in conjunction with and after IronButtonState and IronControlState.

See: Documentation, Demo.

Usage

Installation

npm install --save @polymer/paper-behaviors

Example of using one of the behaviours in a Polymer 3 element

import {PolymerElement, html} from '@polymer/polymer';
import {mixinBehaviors} from '@polymer/polymer/lib/legacy/class.js';
import {PaperButtonBehavior} from '@polymer/paper-behaviors/paper-button-behavior.js';

class SampleElement extends mixinBehaviors([PaperButtonBehavior], PolymerElement) {
  static get template() {
    return html`
      <style>
        :host {
          display: block;
        }
        /* Some properties inherited from the behaviour */
        :host([disabled]) {
          background-color: grey;
          pointer-events: none;
        }
        :host([active]),
        :host([pressed]) {
          background-color: blue;
        }
      </style>
      <div>I am a ripple-y button</div>
    `;
  }
}
customElements.define('sample-element', SampleElement);
