16 Sep 20239 minutes to read

The column menu has options to integrate features like sorting, filtering, and autofit. It will show a menu with the integrated feature when users click on multiple icon of the column. To enable column menu, you need to define the showColumnMenu property as true.

By default, column menu is enabled for all columns and you can disable column menu for a particular column by defining the showColumnMenu as false in columns property.

To use the column menu, inject the ColumnMenu module in the treegrid.

The default items are displayed in following table.

Item	Description
`SortAscending`	Sort the current column in ascending order.
`SortDescending`	Sort the current column in descending order.
`AutoFit`	Auto fit the current column.
`AutoFitAll`	Auto fit all columns.
`Filter`	Show the filter option as given in `filterSettings.type`

app.vue
<template>
<div id="app">
        <ejs-treegrid :dataSource="data" :treeColumnIndex='1' :allowPaging='true' :showColumnMenu='true' childMapping='subtasks'
         :allowFiltering='true' :filterSettings='filterSettings' :allowResizing='true' :pageSettings='pageSettings'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
                <e-column field='taskName' headerText='Task Name' width=180></e-column>
                <e-column field='startDate' headerText=' Start Date' textAlign='Right' :showColumnMenu='false' format='yMd' type='date' width=90></e-column>
                <e-column field='duration' headerText='Duration' textAlign='Right' width=80></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Sort, Resize, ColumnMenu, Page, Filter } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
 data() {
    return {
      data: sampleData,
      filterSettings: { type: "Menu" },
      pageSettings: { pageCount: 4, pageSize: 10 }
    };
  },
  provide: {
      treegrid: [Sort, Resize, ColumnMenu, Page, Filter]
  }
}
</script>

The custom column menu items can be added to the column menu by defining the columnMenuItems as a collection of the MenuItemModel.

The action for custom column menu items can be performed using columnMenuClick event.

In the below example, clear sorting action was performed through columnMenuItems by using clearSorting method of the Tree Grid.

app.vue
<template>
<div id="app">
        <ejs-treegrid ref='treegrid':dataSource="data" :treeColumnIndex='1' :allowPaging='true' :allowSorting='true' :sortSettings='sortSettings' :showColumnMenu='true' childMapping='subtasks' :columnMenuItems='columnMenuItems' :columnMenuClick='columnMenuClick'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
                <e-column field='taskName' headerText='Task Name' width=180></e-column>
                <e-column field='startDate' headerText=' Start Date' textAlign='Right' format='yMd' type='date' width=90></e-column>
                <e-column field='duration' headerText='Duration' textAlign='Right'  width=80></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Sort, ColumnMenu, Page } from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
 data() {
    return {
      data: sampleData,
      columnMenuItems: [{text:'Clear Sorting', id:'clearsorting'}],
      sortSettings: {columns:[{direction: "Ascending", field: "taskID"}]}
    };
  },
  provide: {
      treegrid: [Sort, ColumnMenu, Page]
  },
  methods: {
  columnMenuClick: function(args) {
      if(args.item.id === 'clearsorting'){
        this.$refs.treegrid.clearSorting();
      }
    }
  },
}
</script>

It is possible to customize specific items from the column menu for particular columns using columnMenuOpen event. columnMenuOpen event can be utilized to determine which items to customize in column menu.

The following example shows how to hide the built-in Filter menu item when the column menu is opened for the taskName column, while allowing it to remain visible for all other columns.

app.vue
<template>
<div id="app">
        <ejs-treegrid ref='treegrid':dataSource="data" :treeColumnIndex='1' :allowPaging='true' :allowSorting='true' :showColumnMenu='true' childMapping='subtasks' :columnMenuOpen='columnMenuOpen' :allowFiltering='true' :filterSettings='filterSettings'>
            <e-columns>
                <e-column field='taskID' headerText='Task ID' textAlign='Right' width=90></e-column>
                <e-column field='taskName' headerText='Task Name' width=180></e-column>
                <e-column field='startDate' headerText=' Start Date' textAlign='Right' format='yMd' type='date' width=90></e-column>
                <e-column field='duration' headerText='Duration' textAlign='Right'  width=80></e-column>
            </e-columns>
        </ejs-treegrid>
</div>
</template>
<script>
import Vue from "vue";
import { TreeGridPlugin, Sort, ColumnMenu, Page, Filter} from "@syncfusion/ej2-vue-treegrid";
import { sampleData } from "./datasource.js";

Vue.use(TreeGridPlugin);

export default {
 data() {
    return {
      data: sampleData,
      filterSettings: { type: "Menu" },
    };
  },
  provide: {
      treegrid: [Sort, ColumnMenu, Page, Filter]
  },
  methods: {
   columnMenuOpen: function (args) {
      for (let item of args.items) {
        if (item.text === 'Filter' && args.column.field === 'taskName') {
            item.hide = true;
        } else {
            item.hide = false;
        }
      }
    }
  },
}
</script>
