I can't get my app to duplicate the "Suggest...Define" Menu. I have an ipad 3 and Verision 12.0.4 Go. As for the keyboard, I believe I read somewhere on this website that FileMaker can not currently hide / disable the Keyboard. I have a Bluetooth Keyboard cover and when I turn on the bluetooth keyboard the other keyboard disappears. My test app was created with Filemaker Pro 12 Advance.
There are two 'popup' menu choices, one with uses an editable field and one which does not. I think the name is list vs popup. I don't have time to check this out for an exact post, but if you test with option one vs option two in the Inspector, data tab and field options dialog you might have an answer.
Yes. Choosing a pop-up menu vs a dropdown list did the trick. Also, as far as keyboard suppression, using a Script with Commit Records/Request after I modify the field gets rid of the keyboard and the aggravating toolbar that bounces up.
