Currently, we generate the TOC for a page dynamically after page load through javascript. This is fine for pages with static content. But for pages with dynamic output like /search, sometimes this causes a noticeable page jump due to extensive DOM traversal. Also, the heuristics to calculate the no. of columns is very rudimentary and fills the entire above-the-fold area if the no. of results is very large. Therefore, we generate the TOC from server side itself. And improve the no. of columns heuristic further to accomodate up to 4 columns. This improves page performance and utilizes real estate appropriately according to the input.
