You can check the image representation of touch actions from the below image.

Width

By default, the Kanban is adaptable to its parent container. It can adjust its width of columns based on parent container width. You can also assign width of e-kanban-columns in percentage.

The following code example describes the above behavior.

HTML

<ej-kanban [dataSource]="kanbanData" keyField="Status" [isResponsive]="true" fields.primaryKey="Id" fields.content="Summary" fields.tag="Tags" [query]="query">
    <e-kanban-columns>
        <e-kanban-column key="Open" headerText="Backlog" width="10%"></e-kanban-column>
        <e-kanban-column key="InProgress" headerText="In Progress" width="10%"></e-kanban-column>
        <e-kanban-column key="Close" headerText="Done" width="10%"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

HTML

import { Component } from '@angular/core';
import { NorthwindService } from '../../services/northwind.service';

@Component({
  selector: 'ej-app',
  templateUrl: 'app/components/kanban/default.component.html',
  providers: [NorthwindService]
})
export class DefaultComponent {
  public kanbanData: any;
    constructor(private northwindService: NorthwindService) {
        this.kanbanData = northwindService.getTasks();
        this.query = ej.Query().from('kanbanData').take(30);       
    }
}

NOTE

allowScrolling should be false while defining width in percentage.

Min Width

Min Width is used to maintain minimum width for the Kanban. If the Kanban width is less than minWidth then the scrollbar will be displayed to maintain minimum width.

The following code example describes the above behavior.

HTML

<ej-kanban [dataSource]="kanbanData" minWidth="700" keyField="Status" [isResponsive]="true" fields.primaryKey="Id" fields.content="Summary" fields.tag="Tags" [query]="query">
    <e-kanban-columns>
        <e-kanban-column key="Open" headerText="Backlog" width="120"></e-kanban-column>
        <e-kanban-column key="InProgress" headerText="In Progress" width="110"></e-kanban-column>
        <e-kanban-column key="Close" headerText="Done" width="110"></e-kanban-column>
    </e-kanban-columns>
</ej-kanban>

HTML

import { Component } from '@angular/core';
import { NorthwindService } from '../../services/northwind.service';

@Component({
  selector: 'ej-app',
  templateUrl: 'app/components/kanban/default.component.html',
  providers: [NorthwindService]
})
export class DefaultComponent {
  public kanbanData: any;
    constructor(private northwindService: NorthwindService) {
        this.kanbanData = northwindService.getTasks();
        this.query = ej.Query().from('kanbanData').take(30);       
    }
}

The following output is displayed as a result of the above code example.
