The ToolBar enables you to automatically show or hide items based on the available space.

To manage the behavior of the items that will be rendered in the drop-down list, set their overflow option.

The available overflow values are:

  • (Default) auto
  • always—Always renders the item in the drop-down list.
  • never

The following example demonstrates how show or hide the ToolBar items on resizing.

<div id="vueapp" class="vue-app">
    <div class="col-xs-12 col-sm-12 example-col">

    <kendo-button ref="buttonRef" style="display:none" @click="onClick">Click here to open the window</kendo-button>

    <kendo-window ref="windowRef"
                  :title="'This is Window'">
            <kendo-toolbar-item type="button" text="Button"></kendo-toolbar-item>
            <kendo-toolbar-item type="button" text="Toggle Button" :togglable="true"></kendo-toolbar-item>
