Current behavior I copied code from demo: https://github.com/swimlane/ngx-datatable/blob/master/demo/selection/selection-chkbox.ts#L15

In my template i have checkbox for each row, but in header, the checkbox for “check all or uncheck all” doesn’t appear.

Expected behavior When i use <ngx-datatable-column [width]=“30” [headerCheckboxable]=“true” [checkboxable]=“true”>

Checkbox for check all should appear in header.

Add <[selectionType]=“‘checkbox’”> property to ngx-datatable

Ex :<ngx-datatable class=“material” [rows]=“rowset”
[columnMode]=“‘force’” [headerHeight]=“50” [footerHeight]=“50” [rowHeight]=“‘auto’” [limit]=“10” [selectionType]=“‘checkbox’” (activate)=“onActivate($event)” (select)=‘onSelect($event)’ >
