Setup your development environment

To get started with the ColorPicker component, clone the Essential JS 2 quickstart project using the following commands.

Copied to clipboard
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

The project is preconfigured with common settings (src/styles/styles.css, system.config.js) to start all the Essential JS 2 components.

[src/system.config.js]

Copied to clipboard
System.config({
paths: {
    'npm:': './node_modules/',
    'syncfusion:': 'npm:@syncfusion/'
},
map: {
    app: 'app',

    //Syncfusion packages mapping
    "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
    "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
    "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
    "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
    "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
    "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
    "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
    "@syncfusion/ej2-dropdowns": "syncfusion:ej2-dropdowns/dist/ej2-dropdowns.umd.min.js",
},
packages: {
    'app': { main: 'app', defaultExtension: 'js' }
}
});

System.import('app.ts').catch(console.error.bind(console)).then(function () {
document.getElementById('loader').style.display = "none";
document.getElementById('container').style.visibility = "visible";
});

Add ColorPicker to the project

Add the HTML input tag with ID attribute as the element to your index.html file.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
<title>Essential JS 2 ColorPicker</title>

<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />

<!--style reference from app-->

<!--system js reference and configuration-->
<script src="node_modules/systemjs/dist/system.src.js" type="text/javascript"></script>
<script src="system.config.js" type="text/javascript"></script>

<body>
<div style="margin: 50px;">
    <!--Element which is going to render-->
    <input id="element" type="color" />
</div>

</body>

</html>

Then, import the ColorPicker component in your app.ts file, and initialize it with the #element.

[src/app/app.ts]

Copied to clipboard
import { ColorPicker } from '@syncfusion/ej2-inputs';

// Initializes the ColorPicker component
let colorPicker: ColorPicker = new ColorPicker({}, '#element');

Adding Style sheet to the Application

To render Colorpicker component, need to import inputs and its dependent components styles as given below in styles.css.

Copied to clipboard
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-inputs/styles/material.css";

Run the application

Run the application in the browser using the following command.

Inline type

By default, the ColorPicker will be rendered using SplitButton and open the pop-up to access the ColorPicker. To render the ColorPicker container alone and to access it directly, render it as inline. It can be achieved by setting the inline property to true.

The following sample shows the inline type rendering of ColorPicker.

index.html
styles.css

import { ColorPicker } from '@syncfusion/ej2-inputs';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);

let colorPicker: ColorPicker = new ColorPicker({
    //To render component as inline.
    inline: true,
    showButtons: false
}, '#element');

.wrap {

The showButtons property is disabled in this sample because the control buttons are not needed for inline type. To know about the control buttons functionality, refer to the showButtons sample.
