We are finding that if we put large amounts of selections in a drop down it causes Chrome to say Aw Snap and crash and Edge to freeze entirely (probably because Chrome has better error handling).
Only alternative browsers like Firefox can handle it.
Any way around this besides limiting the data?
I found that I can only list 1042 vendor names from a lookup, as soon as I up it to 1043 or greater it happens every time.
After some testing I found it is not the specific number of lines in the drop down but the total character count.
You can reproduce with either a lookup that returns a lot of data or just copying a large amount of text from notepad into the drop down contents field. But the maximum number of rows can be different depending on how many characters are in the data your listing.
