Directory Structure Not Working/Understandable

[khanfarhan10]

I'm sure that this question has an easy answer, but I absolutely cannot understand the navigation structure.
I was able to get these pages
up and running with all my tabs placed modifying the navigation.yml in the _data directory.
But the problem is that when I open any of the tabs (say projects, posts or courses ) I am only able to view the markdown files under _posts and not under _courses or _projects. So how do I achieve this as all of my tabs are pointing to _posts.

What I am trying to achieve

Projects should show text about recursion under the _projects folder.
Posts should show text about (Something : Might Run) under the _posts folder. (this works fine for now)
Courses should show text about Python course completion under the _courses folder.

I'm running my website locally on ruby but have uploaded it to github pages now : https://khanfarhan10.github.io/ . Thanks in advance, much appreciated. I'm new to Jekyll and ruby.

Now that I have a basic understanding of jekyll, I still don't understand how the posts, research and project pages are generated on my github pages website : khanfarhan10.github.io.

I want to know how to separately add pages for each of them, viz , posts research and projects. The source code is at my repository

Check the docs: https://jekyllrb.com/docs/collections/

You need to explicitly enable collections and render them into pages in your _config.yml:

collections:
  my_collection:
    output: true
  my_another_collection:
    output: true
