It's not implemented in default release. You need to modify NopCommerceStore\Modules\CategoryNavigation.ascx.cs

I have been trying for a long time to implement this, but am not getting anywhere.

I am quite new to c# and not so comfortable yet with nopCommerce.

Is there anyone who can offer guidance or code to this effect?

I have noticed that the current method gets products by parent category Id of 0 which means the main categories.

I have been trying to add a method with the same signature, but no parameters. However, I am not familiar enough with the backend architecture to succeed.  I am getting errors: copied below:

System.Configuration.ConfigurationErrorsException was unhandled by user code
  Message="Method 'GetAllCategories' in type 'NopSolutions.NopCommerce.DataAccess.Categories.SQLCategoryProvider' from assembly 'Nop.DataAccess.SqlServer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation. 
  Source="System.Web"
  BareMessage="Method 'GetAllCategories' in type 'NopSolutions.NopCommerce.DataAccess.Categories.SQLCategoryProvider' from assembly 'Nop.DataAccess.SqlServer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation."

  
I have added GetAllCategories() to CategoryManager.cs and DBCategoryProvider.cs






Any help is highly appreciated. Thanks in advance!!

You should add the same method to SqlCategoryProvider that inherits DBCategoryProvider

Is there any way to display the category and all of its' subcategories expended in the right column in Version 3.40?

The category list can be expanded by updating the CategoryNavigation.cshtml file.

replace

if (category.Id == Model.CurrentCategoryId ||
                category.SubCategories.Count(BreadCrumbContainsCurrentCategoryId) > 0)
            {
                if (category.SubCategories.Count > 0)
                {
            <ul class="sublist">
                @foreach (var subCategory in category.SubCategories)
                {
                    @RenderCategoryLine(subCategory)
                }
            </ul>
                }
            }

with

<!-- Always expand all categories -->
if (true)
            {
                if (category.SubCategories.Count > 0)
                {
            <ul class="sublist">
                @foreach (var subCategory in category.SubCategories)
                {
                    @RenderCategoryLine(subCategory)
                }
            </ul>
                }
            }

Or if you want to selectively expand categories something like this ..

<!-- Always expand the "Products" category and the current category -->
if (category.Id == Model.CurrentCategoryId || category.Name == "Products" ||
    category.SubCategories.Count(BreadCrumbContainsCurrentCategoryId) > 0)
