Partial page transition

HI, I was trying to make a particular type of page transition in which only parts of the page are updated.
I was making a website inspired by the Gmail structure. So there is a list of blogs on the left side(image + title), and when the user clicks on a blog its full content is loaded on the right side(a vertical section) with the left vertical container being unaffected. (No regular loading occurrence just the content update on the right container )
This can be achieved in a static page using scripts but I don’t know how to handle SEO in that case. So can you help me with how can I handle the SEO properly or how can I do the transition?
Thank you
