Dear anhqn,
No, it does absolutely not work, because what you saw was my latest backup which I has to restore from 3.6.5 to get rid of the problem with the resposive menu. The problem, in fact, still persists even with Joomla 3.7.1 and 3.7.2. I got the same issue today again when I tried updating to Joomla 3.7.2.
You won't be able to it in action see it in action again, because I have to keep our website working correctly by restoring it from an operating backup. We can give you access to the administration to try updating yourself. Thanky you.
