I am using Portal for ArcGIS 10.5.1.
I was wondering if there is a way to widen the pop-up box so that the field names are all shown in one line rather than wrapped? I have tried all the different configuration options but cannot find any option to do this.

The Portal Map Viewer does not currently support any customization options to increase the size of pop-up dialogs. Sorry. This functionality has been proposed by other users, please vote for the enhancement on the ArcGIS Ideas site here:
Hope this helps,
