Hm. This is a cool question 🙂
WordPress has a number different controls you can add into the Customizer, and one of them is
dropdown-pages – which is what Edin is using here. There isn’t currently a
dropdown-posts that we could employ, so you’d have to build one on your own (this tutorial looks like it might start you in the right direction).
That’s going to require a fair amount of comfort with PHP/WordPress theming.
If I were you, I’d probably leave Edin as it is, and use a plugin as a workaround.
1. Write your three posts
2. Write a page to go along with those posts – all each one needs
3. Add those three pages as your Featured Pages in the Customizer
So far, you’ve got the normal Edin setup, with some extra pages. Let’s add a plugin.
4. Search for a good redirection plugin
5. Set each of your featured pages to redirect to the corresponding post
6. Do a victory lap
Now Page A will appear on the front page, but when clicked it will actually take people to Post A… and so on.
Let me know if that sounds like a good approach 🙂
I think you’re right. It would be easier for me to leave Edin as it is and use redirection plugin. I could edit the PHP file by myself, but unfortunately it will be a problem when I want to update Edin theme and I have to redo every code again.
Thanks a lot for your help.
If you’re comfortable with making the PHP changes yourself, you can do so in a child theme, then the modifications would be protected in an update 🙂
