I had created a choice column in SharePoint with "or specify value" and then I edited this list in Info-path. I deleted this "Drop-down menu" and added one from Info-path. But now I do not get "Specify value in a text box" option when I publish it. Before editing it in Info-path I had it so that there was a drop-down menu to choose from and if the value did not exist in the drop down then the user would specify it in a drop-box. The only downfall with this was that the drop-down did not update the information once the user enters a specific value. So I thought of using Info-path to provide me a workaround. However, now I do not have the previous functionality at all. Please advise.
Apparently, drop down controls cannot do that OOB. But combo or Multiple Selection List boxes can, if you can use one of those instead.
