I have to search the category name for the product than get it.
https://nimbus.everhelper.me/client/not ... 2aCwwhSI1/

It doesn't display all categories.
I need to fill the category name on the search field to get the category.

I have never seen the category search field before.

Is there any one who know how to get my categories back?

Thanks!

I can't see any problem here, from image you posted I guess you are in add/edit product page and in the links tab you can see attachments to the product like categories etc... In order to add new category attachment you just have to type name of the category to the category text box and hit enter. List of attachments you can see below the text box. I don't know how it worked in older versions but this is just "new way" how to add category attachments nohtnig else.

Hi, Reemon

Would it possible to display full list?
or keep the search field and the full categories list.
It can help to figure the category out.

Below is Opencart Official DEMO Screenshot.
