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 ej-kanban-column in percentage.

The following code example describes the above behavior.

HTML

<template>
    <div>
        <ej-kanban id="Kanban" e-data-source.bind="KanbanData" e-is-responsive="true" e-key-field="Status" e-fields.bind="Field">
            <ej-kanban-column e-header-text="Backlog" e-key="Open" e-width=10%></ej-kanban-column>
            <ej-kanban-column e-header-text="In Progress" e-key="InProgress" e-width=10%></ej-kanban-column>
            <ej-kanban-column e-header-text="Done" e-key="Close" e-width=10%></ej-kanban-column>
        </ej-kanban>
    </div>
</template>

JAVASCRIPT

export class Kanban {
    constructor() {
        this.KanbanData = [

        this.Field = { primaryKey: 'Id', content: 'Summary', tag: 'Tags'};
    }
}

NOTE

e-allow-scrolling 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 e-min-width then the scrollbar will be displayed to maintain minimum width.

The following code example describes the above behavior.

<template>
    <div>
        <ej-kanban id="Kanban" e-data-source.bind="KanbanData" e-is-responsive="true" e-min-width=700 e-key-field="Status" e-fields.bind="Field">
