Displaying products based on multiple categories

Hi
I want to display my product based on several categories. For example, my category tree diagram looks like this:

Products
|---- TV
|---- speaker
|---- hair dryer

Brands
|---- Phillips
|---- Samsung
|---- LG

For example, Philips TV product is in two categories: TV and Philips. How can I display all the products that are in these two categories in the product list type menu?

Hi Philip
This solution takes a long time to create categories. For this, we need to create a category for each household appliance in different brands. For example, the tree diagram of my categories for 5 household appliances in 5 different brands will look like this:

Hairdryer
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

Hairdryer
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

Tea Maker
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

Meat Grinder
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

Television
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

speaker
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

If we can create the possibility of displaying products in 2 separate categories in the menu, there will be no need to create additional categories. We create only 2 categories of brands and household appliances along with their sub-categories. like this:

Household appliances
|---- tea maker
|---- hair dryer
|---- meat grinder
|---- TV
|---- speaker

Brands
|---- Brand 1
|---- Brand 2
|---- Brand 3
|---- Brand 4
|---- Brand 5

I think this will be a valuable feature in Hikashop.
