Adds collapsible behavior to a target element

[![Published on NPM](https://img.shields.io/npm/v/@polymer/iron-collapse.svg)](https://www.npmjs.com/package/@polymer/iron-collapse) [![Build status](https://travis-ci.org/PolymerElements/iron-collapse.svg?branch=master)](https://travis-ci.org/PolymerElements/iron-collapse) [![Published on webcomponents.org](https://img.shields.io/badge/webcomponents.org-published-blue.svg)](https://webcomponents.org/element/@polymer/iron-collapse) ## <iron-collapse> `iron-collapse` creates a collapsible block of content. By default, the content will be collapsed. Use `opened` or `toggle()` to show/hide the content. The aria-expanded attribute should only be set on the button that controls the collapsable area, not on the area itself. See https://www.w3.org/WAI/GL/wiki/Using_aria-expanded_to_indicate_the_state_of_a_collapsible_element#Description `iron-collapse` adjusts the max-height/max-width of the collapsible element to show/hide the content. So avoid putting padding/margin/border on the collapsible directly, and instead put a div inside and style that. ```html

Content goes here...

``` ### Styling The following custom properties and mixins are available for styling: | Custom property | Description | Default | | --- | --- | --- | | `--iron-collapse-transition-duration` | Animation transition duration | `300ms` | See: [Documentation](https://www.webcomponents.org/element/@polymer/iron-collapse), [Demo](https://www.webcomponents.org/element/@polymer/iron-collapse/demo/demo/index.html). ## Usage ### Installation ``` npm install --save @polymer/iron-collapse ``` ### In an html file ```html

Content goes here...

``` ### In a Polymer 3 element ```js import {PolymerElement, html} from '@polymer/polymer'; import '@polymer/iron-collapse/iron-collapse.js'; class SampleElement extends PolymerElement { static get template() { return html`

Content goes here...

`; } } customElements.define('sample-element', SampleElement); ``` ## Contributing If you want to send a PR to this element, here are the instructions for running the tests and demo locally: ### Installation ```sh git clone https://github.com/PolymerElements/iron-collapse cd iron-collapse npm install npm install -g polymer-cli ``` ### Running the demo locally ```sh polymer serve --npm open http://127.0.0.1:/demo/ ``` ### Running the tests ```sh polymer test --npm ```
