I've just found a way to do this with having to only change one line of
code (add an "id" to each section row):

diff --git a/ui-repolist.c b/ui-repolist.c

                     strcmp(section, last_section)))) {

colspan='%d' class='reposection'>",

                        html_txt(section);
                        html("</td></tr>");
                        last_section = section;

With that simple change, I was able to use your pluggable "header"
option to create something that works. The JS isn't exactly something I
would be proud of, but it does accomplish what you've described:

You can compare the two approaches:

 new js hackery: https://git-ap.linaro.org/cgit/
 original patch: https://git-ie.linaro.org/cgit/

My page loads are almost 2x slower with the new approach. However, they
still seem "fast enough".

Let me know what you think, and I can re-submit this one-liner if you
prefer.
