E9 - How to stretch out drop down box

Try changing AutoWidthOption in the properties for the box.
Manual: It will look at the number of pixels entered in the Col1ManualWidth property for how wide to make the dropdown.
ControlWidth: The dropdown will be as wide as the box.
Auto: Epicor will guess how wide to make the dropdown to make the contents fully visible. It's not always correct. If the dropdown for a box spans the width of the screen, change to ControlWidth or Manual to fix it.

E9 - How to stretch out drop down box


In Epicor 9, I have a customization to make. Someone wanted a Reason: drop down box with 5 choices/reasons to select.


I went into developer mode, entered the Reason: label, added an UltraCombo box and entered the 5 choices/reasons.


For some reason, I cannot figure out how to stretch out the reasons. I can stretch out the UltraCombo box itself but not the drop down box with the reason codes. No matter what I change, it stays the same width. 


WHAT AM I DOING WRONG? How do you fix this?
