Maximum number of choices in a dropdown field

Question

Is there a maximum number of choices that can be placed in a dropdown field?

Answer 1

Genevieve,
Many thanks for your quick response. The direct answer is a bit over 400 choices. I know, I know. I’d appreciate any better suggestions.
I’m creating a form to be completed by college instructors in which they indicate their contact info, a course name and number, and information re textbook for that course. I need to pass it along as an Excel sheet with each ROW representing a RECORD for one book. See attached.
My original plan was to have the form first present a choice of subject (e.g., ENG, HIST, POLSCI) and then use a logic rule to pull up the relative small subset of courses under that subject. That went south in a hurry when I imagined what the spreadsheet was going to look like since there has to be a column for each subject area from the first question. If you’d like to look at the much smaller dropdown box in the form I’ve just completed for the summer term, it’s at https://adobeformscentral.com/?f=FocAopnkrTWy8CZaWccckw. I could have four dropdown boxes subsetted according to the division choices in the previous question on the form, but I still end up with a spreadsheet that’s a mess.
I’ve considered having the instructor key in the course number and title, but college faculty are even less reliable than their students.
If you’re more interested than you should be you’ll note that the choices in the dropdown box contain course number, title, and number of students in one field. The target Excel sheet has them in separate fields. I’ll handle that by using text to columns in Excel.
I’d appreciate any wisdom you might share. Since the only way to build the drop down is by copying and pasting each choice, you can see why it occurred to me to ask if there’s a max before doing 401 and then it won’t take the last 10!!
Again, many thanks,
