I have a choice column with over 100 choices, need to give the ability to choose multiple values. Is there a way to make it into a dropdown list with multiple selection? right now the checkbox list is huge and spans multiple pages. or is that a javascript workaround screenshot of column,

i cant use infopath because this is on a document library and not a list

thanks in advance for any ideas you may have.

You need to use HTML and JavaScript/jQuery to create dropdown with checkbox by yourself instead of using the OOB field.
