OK, I changed the width to 274 like you asked and now I have 3 columns so that is what I was looking for, so thank you very much!!
I would like to ask another question since I have your attention on this thread…..
Which plugin would I use to have the categories listed across the top of the page instead of or in addition to the drop down categories?
Like the directory here: https://www.chem.ufl.edu/faculty-and-research/
