From an earlier question (Responsive bootstrap designing in CakePHP 3x) I understand that cakePHP3 are using Foundation for front-end framework, but which version (in cakePHP v.3.2)? I'm struggling with a toggled top-bar, that won't open when minimized. There seems to have been some bugs in the 5th version and I'm now wondering if they aren't fixed in the version that cakePHP3 are using.
The CakPHP application templates base.css file was last updated with foundation on September the 1st of 2015

As far as I can tell, this is version 5.5.2. If you need a newer version, then simply don't use the templates default CSS, there is absolutely no need to stick with what ships with the template.
Also you can file an issue on GitHub and suggest an update, or even create pull request and update it yourself.
