In the Jekyll we generally organised the blogs with the categories.
But how we can create a separate page, in which if we click on business categories then only business related blogs post should be listed.
In which folder we have to create the folder?
I am not aware if this feature is included in the latest jekyll release. A little while ago I created my own solution for this. You can take a look at my theme: classic-jekyll-theme to see how I did it exactly.
The short of it is: create a layout that generates the page, and then create ‘pseudo’ pages to trigger the generation process.
These pseudo pages only need to contain some yaml like:
---
layout: category-page
title: classic
---
This would create a page of all posts in the "classic’ category.
For the generation of the page itself, please take a look at the theme.
Do I need to write this content in the _layout folder by create a new .html file.
Right?
No. Please take a look at my theme. The following information applies to the CLASSIC-JEKYLL-THEME only! (I.e. not to the default Jekyll theme ‘minima’)!!
In the _layouts folder there is a file called category-page.html
This file creates a category page of all posts that refer to a category.
To trigger the generation of a category page you need another file (for example in a pages directory) that specifies the layout generator category-page and specifies for which category it should generate a page. The yaml title is used for the category page.
Please keep in mind that you need my Classic-Jekyll-Theme for this to work.
The reason why I am posting this to point you to an example that can generate category pages. But you will still have to write the generator yourself. Or use my theme 
Does jekyll can create pages for each category automatically?
I want jekyll to create category pages automatically.
