I use this them for a while now and is works great with the FREE drop-down-menu.
I gave 4 Stars because no customizing is possible.
No Auto Install for 5.5
Sorry for the wait!
Looks great and works brilliantly
I am hoping for a 5.5 compatible version in the future.
UPDATE: I have upgraded my site from 220.127.116.11 to 5.5.1 using the built in update feature and can confirm that Boldy Theme + Theme Options Lite + Concrete 5.5.1 work together without any problems.
If you plan to upgrade, follow the instructions and make sure you have a backup just in case.
One of the most well constructed themes I've seen
One of the best themes on C5! Great work.
