You can dynamically change the Kanban columns by using the columns property.

In the below sample, you can dynamically change the allowToggle property at the particular column when you click on the button. You can also change the initially created columns to the new Kanban columns by using the columns property when you click on the button.

app.vue

<template>
  <div id="app">
    <ejs-button
      id="particular_column"
      class="e-btn"
      v-on:click.native="particularColumnClick"
      >Enable Allow Toggle</ejs-button
    >
    <ejs-button id="column" class="e-btn" v-on:click.native="columnClick"
      >Change Columns</ejs-button
    >
    <ejs-kanban
      ref="KanbanObj"
