I have been using Sectioned View plugin to create a view with two columns (two List View sections). This has worked fine. I'm very pleased with the output.
I was wondering if I could fit three columns into a view, and still keep it readable. I created three simple List View sections: One, Two, and Three. I aligned them left, center, and right respectively, and set width to 1/3 each.
I was expecting to see each section side by side, but instead, they were positioned one after another (threeColumns.png).
