I actually just created the simple dropdown list from the content control. I am using Office 2016. It is basically a list for 175 items. I think it is too much but that is what is required. The document will be saved as a template, so that users will put in their content, and then if they need to select an item from the list they will go to the custom tab in their ribbon, and then click on the dropdown list, select and item from the list and input it into their document. Now there is no way for me to know where they will be inputting the item in the document, so that is what I was trying to figure out. I don't think using bookmarks or a form would have helped in this case.
