Hello Jinesh,

Your question isn't entirely clear to me but I'll try to help you out.

You can do the following in your cshtml file:

@{
    var mainCategories = CurrentPage.AncestorOrSelf(1).Descendants("MainCategoryAlias");
}
<ul>
    @foreach (var category in mainCategories)
    {
        <li>
            @category.Name
            @if (category.Children.Any())
            {
                <ul>
                    @foreach (var subCategory in category.Children)
                    {
                        <li>
                            @subCategory.Name
                            @if (subCategory.Children.Any())
                            {
                                <ul>
                                    @foreach (var product in subCategory.Children)
                                    {
                                        @product.Name
                                    }
                                </ul>
                            }
                        </li>
                    }
                </ul>
            }
        </li>
    }
</ul>

Hope this helped you out a little!

Kind regards,

Jochen
