First thanks for making this project, it's really a great addition to django-admin, my clients are thrilled ...
I was previsouly using chosen (through django-chosen), but I don't understand why the chosen select in your app are not taking the width they should. Chosen code is made to let them grow as necessary, but in the django admin, they all have the same width and options get cropped or stacked on two lines, nearly unusable.
Did you force the CSS width of these selects somewhere ?
Should the Chosen library be updated ?
