Hi Alexander,
I found an issue when
A Form is EDIT
A Form is being displayed as a child form
A field is a Choice field
The field is conained in a GRID
The form has “responded” to the smaller size of the child form
When the above is true, the drowndown gets collapsed horizontally so it is not possible to see any choices.
NOTE: If the form is edited without it being in shown as a “child” then there is no issue.
I have sent you an email with screenshots which hopefully explains the bug.
Best regards
/Marcus
