Need additional category box in WordPress site

[sunnyujjawal]

I want to add an additional function like category addition while new post so that while publishing new post i can select both category and my additional box option also.

Like i am selecting category only i get this URL:

sitename.com/category/business - it will display my all posts in this category

and simultaneously i need the same post in other category box whose URL will be like this:

sitename.com/custom-keyword/shopping

Please don't suggest to select multiple category from single category box, i need different custom URLs

Could you maybe use tags to perform that function?

Post lives in sitename.com/category/business

And also tagged as "widgets"

So, sitename.com/tags/widgets would also display the posts.

You could remove the /tags/ folder via settings.

But i don't want category or tag in URL

You want 2 different URLs with the same content (the actual post or posts within that category)?

You can remove the /category and /tag from the URL structure (the Yoast SEO plugin lets you do this). Then your link structure would just be sitename.com/your-category-or-tag/your-post-url.

Not 100% sure what you are asking here.

sitename.com/category/business - a category page that displays all "business" categories"

And you want a secondary category page:

sitename.com/custom-keyword/shopping

Where "custom-keyword" is defined by you and "shopping" is a category? Or is "shopping" the post URL?

I think tags would still be your best option if you want a custom folder name for groups of posts.
