I think this is not possible directly with Form components as API states
The application can request that the implementation use a particular input mode when the user initiates editing of a TextField or TextBox. The input mode is a concept that exists within the user interface for text entry on a particular device. The application does not request an input mode directly, since the user interface for text entry is not standardized across devices.
You would be able to do it with Canvas if you do all the hard coding. Question is, if this is worth the effort?
If there is possibility to manipulate this behaviour I would like to know this too.
