Is it possible to declare a set of rows to expanded by default?

[roberthelmick08]

@ticklemycode you could achieve this by doing something similar to below. It filters rows by rowIndex (or any other property) then iterates through the filtered rows and changes the expanded property.

rows.filter(temp => temp.rowIndex > 0 && temp.rowIndex < 10).map(row => {
    row.expanded = true;
}

Don’t forget to define expanded and rowIndex in your html template:

<ngx-datatable-column name="" [width]="22" [minWidth]="22" [maxWidth]="22" [frozenLeft]="true">
    <ng-template let-row="row" let-expanded="expanded" let-rowIndex="rowIndex" ngx-datatable-cell-template></ng-template>
        // ...
</ngx-datatable-column>

This is just off the top of my head, so it may require some tweaking, but the idea is that you would iterate through the array of rows and set the expanded properties to true;
