I have a SharePoint list with a customized form (not a canvas form). The list currently has 3,000 items in it. As a rule, I will be searching or filtering for only 1 item at a time in that list -- a specific order number.
Is there a limit to the number of lines I can use with a customized form? If so, what issues might I run into. Of course, I am experiencing some slowness, but would like to better understand what else might arise.
Thank you.
