I'm having odd issues with display options in the new Forms. The options are working as intended in edit mode, but when moving into preview or the live site the display options are ignored. I've made sure that I've published everything so that shouldn't be the issue. I'm using display options for Bootstrap similar to the Alloy implementation and they work as they should on the rest of the site features. For the form styles I'm using a slightly modified version of Mikko Huilaaja's Bootstrap styles (https://github.com/huilaaja/EpiserverFormsWithBootstrap).
The Form in Edit mode.
The Form on the live site.
Any ideas on what could be causing this or a possible fix?
I have faced the same thing. The solution would be to create a custom TextBlockElement with width and position(right or left). It satisfy my requirement.
