Thank you for your post.
With the proper privilege set, you can set the Container field to be View Only. That is, create a Privilege Set that gives you normal access, but change the Container field settings from Modifiable to View Only. Then, in FileMaker Go, when you tap the field, you will only have two options: Open and Email.
If you don't want the user to have the Email option, then make the field a button that switches you to another layout that displays the contents of the Container field in full screen, and have a back button to return to the previous layout.
Let me know if you need additional clarification.
