[![Published on NPM](https://img.shields.io/npm/v/@polymer/iron-dropdown.svg)](https://www.npmjs.com/package/@polymer/iron-dropdown) [![Build status](https://travis-ci.org/PolymerElements/iron-dropdown.svg?branch=master)](https://travis-ci.org/PolymerElements/iron-dropdown) [![Published on webcomponents.org](https://img.shields.io/badge/webcomponents.org-published-blue.svg)](https://webcomponents.org/element/@polymer/iron-dropdown) ## <iron-dropdown> `` displays content inside a fixed-position container, positioned relative to another element. See: [Documentation](https://www.webcomponents.org/element/@polymer/iron-dropdown), [Demo](https://www.webcomponents.org/element/@polymer/iron-dropdown/demo/demo/index.html). ## Usage ### Installation ``` npm install --save @polymer/iron-dropdown ``` ### In an HTML file ```html

``` ### In a Polymer 3 element ```js import {PolymerElement, html} from '@polymer/polymer'; import '@polymer/iron-dropdown/iron-dropdown.js'; class SampleElement extends PolymerElement { static get template() { return html` `; } _openDropdown() { this.$.dropdown.open(); } } customElements.define('sample-element', SampleElement); ``` In the above example, the `

` assigned to the `dropdown-content` slot will be hidden until the dropdown element has `opened` set to true, or when the `open` method is called on the element. ## 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-dropdown cd iron-dropdown 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 ```
