As you can see we in our blog also use sidebar for Dynamic View! Sidebar is best as SEO is concerned!
It is also the only template in Dynamic View that allows you to view the content of a post while still maintaining the complete list of posts in the sidebar! It uses AJAX for this! The posts in sidebar are shown upto screen limit without scrollbar! Better load all the past posts in scrollbar by this easy and simple method!
We in our blog also use it!
To add scroll-bar follow this simple step:-
Go to Dashboard --> Template --> Customize --> Advanced --> Add CSS --> Paste the following code --> Press enter After the last character of the last line --> Apply to Blog.
