Auto Create Columns Using Single Plain List
问题 I am trying to write flexible code where I have one plain <ul> which gets automatically creates another column for every 5th element. I have found a tutorial that achieves this but places the items in a horizontal order whereas I require a vertical order. I have seen some other tutorials that outputs a vertical order, but also attaches class="first" and class="second" to each li which is not what I want. I am looking to do with with my existing HTML code. What I Want: -01 -06 -11 -02 -07 -12
