Customizable sidebar – Blog post

Hello,

Me and my client are wondering if it is possible to include buttons or images in the sidebar where you can see the categories, in every blog posts.

The website has 3 main sections (Info/Contact/Therapy) which have a specific visual associated with them. I would like to have buttons above or below the categories that redirect to specific pages.

Please note that these 3 categories are not in the main header. This is why I am wondering if there is a way to add them to each individual blog posts without being in the post itself.

I am using Elegant Divi 2.0 theme.

I hope what I’m trying to say is clear, if not, let me know and I will try to explain more!

Thanks in advance,

Jean-Philippe
