In the last tutorial, we showed you how to remove the current categories so you can add your own. Categories allow you to group products together so your shopping cart visitors can find products that are related to one another. It's best practice to plan out your product categories ahead of time but you can edit, remove, and add new categories at any time. 

We're creating a fictitious online technology bookstore for our tutorial. We've already set up some basic categories in our shopping cart. However, we're going to set up a new category called "Databases."

  1. Log into your OpenCart Dashboard
  2. Go to Catalog > Categories
  3. Select the "Insert" button in the upper right corner.
  4. On the General Tab, fill in the fields for your new category (you can make changes at any time). The only field that is required is the "Category Name"
  5. categories_2

  6. Click on the Data Tab and fill in the fields you want (these are optional).
  7. categories_3

  8. Click on the Design Tab and select from the dropdown menu if you want (these are optional). 
  9. categories_4

  10. Click the "Save" button in the upper right corner.

At this point you have created your first category! You can add as many categories as you would like. The following screenshot shows that the category was successfully created.

Hi, my products are not displaying under my categories. I did all the steps correctly. 

I can't seem to add categories to my store. I can add products, but I want similar products in the same category. 


Any help would be appreciated.

Hello Sarah, and thank you for your comment.

Are you able to see already existing categories in OpenCart and just not create any new ones?

It sounds like you might be missing one of the required fields that you need to fill out while creating a category. Are you getting any errors when you are unable to add a new category?

Make sure for instance if you've got more than 1 language installed for OpenCart that you are entering in the Category Name field for each language tab.

Please let us know any additional information that you have that could help us try to replicate this problem so we can help you fix it.

In the newest version of OpenCart (2.0), you could change the category by visiting the product within the administration area, clicking on the Links tab, and adjusting your categories there.

Hello Ray,

I'm sorry you're having problems with the OpenCart. We do need more information in order for us to assist you, please. Can you please provide any error messages? Screenshots of the problem you're seeing? Also, the exact steps you're taking to get to the problem, and if you have installed any plugins would help us. I am running OpenCart and it's able to add products in a category. So I am currently unable to duplicate your problem. Please provide us more information and we would be happy to assist you further.

Are you getting any error messages? Are the categories you are adding under parent categories that you may have to go deeper into?

There are no error messages.

This is what happens:

I add 8 categories.

All 8 categories correctly show up on the navigation bar.

Then I add a product.  When I go to add a link and click "categories",

only 5 categories show in the drop down box.

I've done some research on the issue as a large majority of people running OpenCart are experiencing the same thing. It appears that it is a bug within OpenCart itself and you may have the best luck on the OpenCart forums as someone may have a custom solution to fix the bug.

Based on the research I have done, it may be a bug within OpenCart itself that is causing this. Posting on the OpenCart forums may lead you to further information on the issue.

So, this has been going on for over a year and hasn't been fixed? I am on a new install and having the same issue, no matter what catagoiries and subcatagories I add, I can only see the original defaut catagories that were installed with the software when I try to add products.  Not very promising...

Hello Mike,

I was not able to replicate the issue of only seeing the default categories. Have you tried clearing your browsers cache as that may be the cause of this issue.

Kindest Regards,

Hello shanibb,

Thank you for your question. We are happy to help, but will need some information to help narrow down the cause.

What happens when you add a category/subcategory?

Do you get any errors? What are they?

Do you get a blank screen?

What 3rd party addons/themes are you using?

Thank you,
