multiple taxonomies?

Hi,

I have multiple taxonomies for examples Genres (Comedy, Thriller) and ProductGroups (DVD, BluRay).

I want customers to be able to browse products byGenre and by ProductGroup.

To achieve this I create a Category structure like below:

> Genres
> Comedy
   > Romantic Comedy
   ...
  > Thriller
  ...
> ProductGroups
  > DVD
   >  DVD rental
   ...
  > BluRay
  ...

(If there's a better way to do this, please let me know.)

Now instead of CategoryNavigation.ascx displaying the complete Category tree, I would like to place two instances of the CategoryNavigation.ascx, one with the root Category set to Genres and one with the root Category set to ProductGroups.

Is this possible out of the box or do I need to do custom coding?

Thanks!

Would be nice if you could optionally set the RootCategoryID?

<nopCommerce:CategoryNavigation ID="ctrlCategoryNavigation" runat="server" RootCategoryID="123" />

Hi  I have just implimented a solution to this need in 1.90.

The affected files are :

CategoryNavigation.ascx and CategoryNavigation.ascx.cs as well as the necessary master page/s.

Replace all code in CategoryNavigation.ascx.cs with:

Then replace the code in CategoryNavigation.ascx with:


<%@ Control Language="C#" AutoEventWireup="true"
    Inherits="NopSolutions.NopCommerce.Web.Modules.CategoryNavigation" Codebehind="CategoryNavigation.ascx.cs" %>
<div class="block block-category-navigation">
    <div class="title">
        <asp:PlaceHolder runat="server" ID="phRootCategoryName" EnableViewState="false" />
    </div>
    <div class="clear"></div>
    <div class="listbox">
        <ul>
            <asp:PlaceHolder runat="server" ID="phCategories" EnableViewState="false" />
        </ul>
    </div>
</div>




Last step is to modify your master page/s (threecolumn.master) by modding the code as below:


            <nopCommerce:CategoryNavigation ID="ctrlCategoryNavigation" runat="server" />
            <div class="clear">
            </div>
or
            <nopCommerce:CategoryNavigation ID="ctrlCategoryNavigation1" runat="server" RootCategoryID="30" />
            <div class="clear">
            </div>
            <nopCommerce:CategoryNavigation ID="ctrlCategoryNavigation2" runat="server" RootCategoryID="34"/>
            <div class="clear">
            </div>
            <nopCommerce:CategoryNavigation ID="ctrlCategoryNavigation3" runat="server" RootCategoryID="43"/>
            <div class="clear">
            </div>


Hope this helps.
