DevExtreme Vue - Column Chooser

The column chooser allows a user to change the set of columns at runtime. It is configured using the columnChooser object and may operate in two modes: the default drag-and-drop mode and the select mode designed for touch devices.

jQuery
JavaScript
$(function() {
    $("#treeListContainer").dxTreeList({
        columnChooser: {
            enabled: true,
            mode: "dragAndDrop" // or "select"
        }
    });
});
Angular
HTML
TypeScript
<dx-tree-list ... >
    <dxo-column-chooser
        [enabled]="true"
        mode="dragAndDrop"> <!-- or "select" -->
    </dxo-column-chooser>
</dx-tree-list>
import { DxTreeListModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxTreeListModule
    ],
    // ...
})

Set a column's allowHiding option to false if it should never be hidden. For columns whose headers should never appear in the column chooser, set the showInColumnChooser option to false.

jQuery
JavaScript
$(function() {
    $("#treeListContainer").dxTreeList({
        columnChooser: { enabled: true },
        columns: [{
            // ...
            allowHiding: false // cannot be hidden
        }, {
            // ...
            showInColumnChooser: false // does not appear in the column chooser even when hidden
        }]
    });
});

<dx-tree-list ... >
    <dxo-column-chooser [enabled]="true"></dxo-column-chooser>
    <dxi-column ...
        [allowHiding]="false"> <!-- cannot be hidden -->
    </dxi-column>
    <dxi-column ...
        [showInColumnChooser]="false"> <!-- does not appear in the column chooser even when hidden -->
    </dxi-column>
</dx-tree-list>
import { DxTreeListModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxTreeListModule
    ],
    // ...
})

Call the showColumnChooser() or hideColumnChooser() method to control the column chooser programmatically.

jQuery
JavaScript
var treeList = $("#treeListContainer").dxTreeList("instance");
treeList.showColumnChooser();
treeList.hideColumnChooser();
Angular
TypeScript
import { ..., ViewChild } from "@angular/core";
import { DxTreeListModule, DxTreeListComponent } from "devextreme-angular";
// ...
export class AppComponent {
    @ViewChild(DxTreeListComponent, { static: false }) treeList: DxTreeListComponent;
    // Prior to Angular 8
    // @ViewChild(DxTreeListComponent) treeList: DxTreeListComponent;
    showColumnChooser () {
        this.treeList.instance.showColumnChooser();
    };
    hideColumnChooser () {
        this.treeList.instance.hideColumnChooser();
    };
}
@NgModule({
    imports: [
        // ...
        DxTreeListModule
    ],
    // ...
})
