First of all many many thanks to the developers of this snippet. I am using Wayfinder for a dropdown menu on a couple of sites and it has been serving me very well.
I noticed a little glitch however when a dropdown (parent) only contains one subpage (child). In that case it does not seem to get the class="last" assigned.
Obviously this results in some css styling issues when using a border to form a box around a dropped down menu as the screenshots i have attached to this post show.
Anyone has some ideas about how I could solve this?
