Kanban - HTML UI Elements for Mobile & Web Applications | www.HtmlElements.com

Overview

Smart.Kanban represents a kanban board that visually depicts work at various stages of a process using cards to represent tasks and columns to represent each stage of the process.

Getting Started with Kanban Web Component

Smart UI for Web Components is distributed as smart-webcomponents NPM package. You can also get the full download from our website with all demos from the Download page.

Setup the Kanban

Smart UI for Web Components is distributed as smart-webcomponents NPM package

  1. Download and install the package.

    npm install smart-webcomponents

  2. Once installed, import the Kanban module in your application.

    <script type="module" src="node_modules/smart-webcomponents/source/modules/smart.kanban.js"></script>

  3. Adding CSS reference

    The smart.default.css CSS file should be referenced using following code.

    <link rel="stylesheet" type="text/css" href="node_modules/smart-webcomponents/source/styles/smart.default.css" />

  4. Add the Kanban tag to your Web Page

    <smart-kanban id="kanban"></smart-kanban>

  5. Create the Kanban Component

    	<script type="module">
    		Smart('#kanban', class {
    			get properties() {
    				return {
    			    collapsible: true,
    				dataSource: window.getKanbanData(),
    				columns: [
    					{ label: 'To do', dataField: 'toDo' },
    					{ label: 'In progress', dataField: 'inProgress' },
    					{ label: 'Testing', dataField: 'testing' },
    					{ label: 'Done', dataField: 'done' }
    				]
    			}
    			}
    		});
    	</script>	   
    		

    Another option is to create the Kanban is by using the traditional Javascript way:
    	const kanban = document.createElement('smart-kanban');
    
    	kanban.disabled = true;
    	document.body.appendChild(kanban);
    		

    Smart framework provides a way to dynamically create a web component on demand from a DIV tag which is used as a host. The following imports the web component's module and creates it on demand, when the document is ready. The #kanban is the ID of a DIV tag.

    	import "../../source/modules/smart.kanban.js";
    
    	document.readyState === 'complete' ? init() : window.onload = init;
    
    	function init() { 
    		const kanban = new Smart.Kanban('#kanban', {
    			    collapsible: true,
    				dataSource: window.getKanbanData(),
    				columns: [
    					{ label: 'To do', dataField: 'toDo' },
    					{ label: 'In progress', dataField: 'inProgress' },
    					{ label: 'Testing', dataField: 'testing' },
    					{ label: 'Done', dataField: 'done' }
    				]
    			});
    	}
    	

  6. Open the page in your web server.

Tasks

In Smart.Kanban data loaded from the data source is visualized via task cards displayed in columns. Tasks have various properties reflected in the cards. Details abount these are listed below.

  1. Text - corresponds to the data source text field.
  2. Completed sub-tasks - corresponds to the data source checklist field. Visiblity contolled by property taskProgress and whether sub-tasks are defined.
  3. Progress - corresponds to the data source progress field. Visiblity contolled by property taskProgress.
  4. User icon - corresponds to the data source userId field. Visiblity contolled by property taskUserIcon.
  5. Comments icon - opens the Comments list with comments corresponding to the data source comments field. Visiblity contolled by property taskComments.
  6. Actions icon - opens the Actions list (Edit/Copy/Remove). Visiblity contolled by property taskActions.
  7. Tags - corresponds to the data source tags field. Visiblity contolled by property taskTags.
  8. Due date - corresponds to the data source dueDate field. Visiblity contolled by property taskDue.
  9. Priority icon - by default, shown only for low and high priority. Corresponds to the data source priority field. Visiblity contolled by property taskPriority.
  10. Color band - corresponds to the data source color field. If color is not set, the theme's primary color is applied.

Task Drag/Drop

Smart.Kanban allows the dragging and dropping of tasks if the properties allowDrag and allowDrop are enabled (which, by default, they are).

Multiple tasks can be dragged simultaneously by selecting them first (in selectionMode: 'zeroOrManyExtended').

Column Collapsing

The columns of Smart.Kanban can be collapsed to make more space or highlight other columns. However, one column always remains expanded. Collapsing can be disabled by setting collapsible to true. To disable collapsing for particular columns only, set collapsible to false in their column definitions.

Column Orientation

Tasks in columns can either be vertically (default) or horizontally ordered. The orientation property can be applied in the column definition.

columns: [
    { label: 'To do', dataField: 'toDo', orientation: 'horizontal' },
    { label: 'In progress', dataField: 'inProgress', orientation: 'vertical' },
    { label: 'Done', dataField: 'done', orientation: 'horizontal' }
]

Resizing

Smart.Kanban is built upon the CSS Grid Layout technology which allows the component to seemlessly resize with minimum JavaScript calculations. This makes Kanban particularly useful when viewed on mobile devices.

Create, Append, Remove, Get/Set Property, Invoke Method, Bind to Event


Create a new element:
	const kanban = document.createElement('smart-kanban');
	

Append it to the DOM:
	document.body.appendChild(kanban);
	

Remove it from the DOM:
	kanban.parentNode.removeChild(kanban);
	

Set a property:
	kanban.propertyName = propertyValue;
	

Get a property value:
	const propertyValue = kanban.propertyName;
	

Invoke a method:
	kanban.methodName(argument1, argument2);
	

Add Event Listener:
	const eventHandler = (event) => {
	   // your code here.
	};

	kanban.addEventListener(eventName, eventHandler);
	

Remove Event Listener:
	kanban.removeEventListener(eventName, eventHandler, true);
	

Using with Typescript

Smart Web Components package includes TypeScript definitions which enables strongly-typed access to the Smart UI Components and their configuration.

Inside the download package, the typescript directory contains .d.ts file for each web component and a smart.elements.d.ts typescript definitions file for all web components. Copy the typescript definitions file to your project and in your TypeScript file add a reference to smart.elements.d.ts

Getting Started with Angular Kanban Component

Setup Angular Environment

Angular provides the easiest way to set angular CLI projects using Angular CLI tool.

Install the CLI application globally to your machine.

npm install -g @angular/cli

Create a new Application

ng new smart-angular-kanban

Navigate to the created project folder

cd smart-angular-kanban

Setup the Kanban

Smart UI for Angular is distributed as smart-webcomponents-angular NPM package

  1. Download and install the package.
    npm install smart-webcomponents-angular
  2. Once installed, import the KanbanModule in your application root or feature module.

    app.module.ts

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    
    import { KanbanModule } from 'smart-webcomponents-angular/kanban';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [ AppComponent ],
        imports: [ BrowserModule, KanbanModule ],
        bootstrap: [ AppComponent ],
    	entryComponents: [ AppComponent ]
    })
    
    export class AppModule { }
    	

  3. Adding CSS reference

    The following CSS file is available in ../node_modules/smart-webcomponents-angular/ package folder. This can be referenced in [src/styles.css] using following code.

    	@import 'smart-webcomponents-angular/source/styles/smart.default.css';

    Another way to achieve the same is to edit the angular.json file and in the styles add the style.

    	"styles": [
    		"node_modules/smart-webcomponents-angular/source/styles/smart.default.css"
    	]
    	
  4. Example


    app.component.html

     
    <smart-kanban #kanban id="kanban" [collapsible]="collapsible" [dataSource]="dataSource" [columns]="columns">
    </smart-kanban>
    		

    app.component.ts

     
    import { Component, ViewChild, OnInit, AfterViewInit, ViewEncapsulation } from '@angular/core';
    import { KanbanComponent } from 'smart-webcomponents-angular/kanban';
    import { GetKanbanData } from '../../common/data';
    
    
    @Component({
        selector: 'app-root',
        templateUrl: './app.component.html',
        styleUrls: ['./app.component.css'],
        encapsulation: ViewEncapsulation.None
    })
    
    export class AppComponent implements AfterViewInit, OnInit {
        @ViewChild('kanban', { read: KanbanComponent, static: false }) kanban: KanbanComponent;
    
        collapsible = true;
        dataSource = GetKanbanData();
        columns = [
            { label: 'To do', dataField: 'toDo' },
            { label: 'In progress', dataField: 'inProgress' },
            { label: 'Testing', dataField: 'testing' },
            { label: 'Done', dataField: 'done' }
        ];
    
        ngOnInit(): void {
            // onInit code.
        }
    
        ngAfterViewInit(): void {
            // afterViewInit code.
            this.init();
        }
    
        init(): void {
            // init code.
    
    
    
        }
    }
    		

    app.module.ts

     
    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    
    import { KanbanModule } from 'smart-webcomponents-angular/kanban';
    
    import { AppComponent } from './app.component';
    
    @NgModule({
        declarations: [ AppComponent ],
        imports: [ BrowserModule, KanbanModule ],
        bootstrap: [ AppComponent ],
    	entryComponents: [ AppComponent ]
    })
    
    export class AppModule { }

Getting Started with React Kanban Component

Setup React Environment

The easiest way to start with React is to use create-react-app. To scaffold your project structure, follow the installation instructions.

	npm install -g create-react-app
	create-react-app my-app
	cd my-app
	npm start
	

Preparation

Open src/App.js andsrc/App.css

  1. Remove everything inside the App div tag in src/App.js:
    <div className="App"> </div>
  2. Remove the logo.svg import
  3. Remove the contents of src/App.css
  4. Remove src/logo.svg

Setup the Kanban

Smart UI for React is distributed as smart-webcomponents-react NPM package

  1. Download and install the package.
    npm install smart-webcomponents-react
  2. Once installed, import the React Kanban Component and CSS files in your application and render it app.js

    import 'smart-webcomponents-react/source/styles/smart.default.css';
    import React from "react";
    import ReactDOM from "react-dom";
    import { Kanban } from 'smart-webcomponents-react/kanban';
    import { GetKanbanData } from './common/data';
    
    class App extends React.Component {
    	dataSource = GetKanbanData();
    	columns = [{
    		label: 'To do',
    		dataField: 'toDo'
    	},
    	{
    		label: 'In progress',
    		dataField: 'inProgress'
    	},
    	{
    		label: 'Testing',
    		dataField: 'testing'
    	},
    	{
    		label: 'Done',
    		dataField: 'done'
    	}
    	]
    
    	componentDidMount() {
    
    	}
    
    	render() {
    		return (
    			<div>
    				<Kanban ref="kanban"
    					columns={this.columns}
    					dataSource={this.dataSource}
    					collapsible>
    				</Kanban>
    			</div>
    		);
    	}
    }
    
    ReactDOM.render(<App />, document.querySelector("#root"));
    
    export default App;
    	

Running the React application

Start the app with
npm start
and open localhost:3000 in your favorite web browser to see the output.

Getting Started with Vue Kanban Component


Setup Vue Environment

We will use vue-cli to get started. Let's install vue-cli

npm install -g @vue/cli

Then we can start creating our Vue.js projects with:

vue create my-project

Setup the Kanban

Open the "my-project" folder and run:

npm install smart-webcomponents

Setup with Vue 3.x

  • Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

    Open src/main.js in your favorite text editor and change its contents to the following:

    main.js

    import { createApp } from 'vue'
    import App from './App.vue'
    
    const app = createApp(App)
    
    app.config.isCustomElement = tag => tag.startsWith('smart-');
    app.mount('#app')
    		
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue

    <template>
      <div class="vue-root">
        <smart-kanban id="kanban"></smart-kanban>
      </div>
    </template>
    
    <script>
    import { onMounted } from "vue";
    import "smart-webcomponents/source/styles/smart.default.css";
    import "smart-webcomponents/source/modules/smart.kanban.js";

    We can now use the smart-kanban with Vue 3. Data binding and event handlers will just work right out of the box.

Setup with Vue 2.x

  • Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.

    Open src/main.js in your favorite text editor and change its contents to the following:

    main.js

    import Vue from 'vue'
    import App from './App.vue'
    
    Vue.config.productionTip = false
    Vue.config.ignoredElements = [
    'smart-kanban'
    ]
    
    new Vue({
      render: h => h(App),
    }).$mount('#app')
  • Open src/App.vue in your favorite text editor and change its contents to the following:

    App.vue

    <template>  
    	  <smart-kanban id="kanban"></smart-kanban>  
    	 </template>   
    	 <script>  
    	 import "smart-webcomponents/source/styles/smart.default.css";  
    	 import 'smart-webcomponents/source/modules/smart.kanban.js';

    We can now use the smart-kanban with Vue. Data binding and event handlers will just work right out of the box.
