<h3>HTML in Row Details</h3>
<p>
This grid shows product categories on each row. Expanding
the rows shows an HTML element with information about
the products in that category:
</p>
<wj-flex-grid [itemsSource]="categories" [isReadOnly]="true">
<wj-flex-grid-column [header]="'Name'" [binding]="'CategoryName'"></wj-flex-grid-column>
<wj-flex-grid-column [header]="'Description'" [binding]="'Description'" [width]="'*'"></wj-flex-grid-column>
<ng-template wjFlexGridDetail [isAnimated]=true let-item="item">
ID: <b>{{item.CategoryID}}</b><br />
Name: <b>{{item.CategoryName}}</b><br />
Description: <b>{{item.Description}}</b><br />
Products: <b>{{getProducts(item.CategoryID).length}} items</b><br />
<ol>
@for (p of getProducts(item.CategoryID); track p;) {
<li>{{p.ProductName}}</li>
}
</ol>
</ng-template>
</wj-flex-grid>
<h3>Grids in Row Details</h3>
<p>
You can add anything you want to the detail rows,
including other grids. This example shows the same
categories, but the detail row uses another grid
to show the products:
</p>

<wj-flex-grid-column [header]="'Category Name'" [binding]="'CategoryName'" [width]="'*'"></wj-flex-grid-column>
