Re: "+" to "_"
Hi,
ah now I understand what you mean.
There might or might not be an option, but with bootstrap an all the new things, I would rather suggest to develop an "Off-Canvas" menu based on one of those free jQuery Plugins (maybe with a non-java-script fall-back, which I recommend strongly for accessibility reason).
This will maybe not the easiest way to do for the first time, but in the very end, I imagine a solution lookingnd feeling much times nicer and fancier than a possible click-on/off option.
I'd suggest to Off-Canvas the whole column in the template directly ...
Anyway: there is an option to allow to toggle the menu!
Thus it must exist (or be easy to implement) an option to togggle by default.
I suggest you check out aswell at /tiki-admin_menus.php as in the module specific configuration at /tiki-admin_modules.php where you applied the module for the menu.
Regards,
Torsten
