I have a list customized using InfoPath, The list has a dropdown list when the user selects this dropdown list, it brings huge data from an external list/data source and populated in this dropdown list. As we know drop-down list character limit is 255 and users are not able to submit the form. Is there anyone worked around this? Is that possible to cut/limit 255 characters in this dropdown after a user selects from a drop-down field? Thanks, Gashaye

You have two options.

  1. Use a substring function to limit the characters in the drop-down
  2. Convert the drop-down to a multi-line text field that allows for more characters.

Drop down list to multiple of text maximizing 255 characters

Text Formula like substring (InfoPath)
