Increasing Limit of Silo Navigation Widget

CrushL · Jan 30, 2014

Hello,

I'm currently experimenting with different silo themes and plugins and have a problem with a little plugin that creates silo navigation on a widget. The problem is: It only shows a maximum of 10 entrys in its navigation ("Home" + 9 Silos). I guess there should be an entry somewhere in that code for the maximum number, but I'm really not good in coding so I figured I ask you guys on here. I tried to change some array numbers from 10 to 20, but with no effect (numbers i changed are located at the bottom of the first part, but for this post I set everything back to default). So here is the code of the plugin (split in 2 files):
