How can I sort a list into categorys?

Hi all,

I wonder if I can sort this list in to category. I want to make a list that only shows the pipes. How can i do that?

This should do it. We are getting the elements as string and figuring out if it contains “Pipe”.

Or this is a more clever way. This will group the categories then you can use a get item at index node.2015-09-14_09h08_46
