Ability to vary the width of a dropdown selection box.
Currently the width of a dropdown selection field on a customer field is determined by the width of the field in the layout. Standard fields like Product have dropdowns with a wider 40 character viewing window which allows for easier record selection. If this functionality can be added to customer fields it would improve the usability.

We were adding a product picker based on a custom Product group field added to the product file. The user first selects the product group from a picklist which in turn filters the product picker field. However although we only need to populate the product code I don't want to waste screen real estate by stretching the product picker field to get move characters per line when it can easily be extended under the line as is the case with the product field in Sales Opportunities.
