I have a HTML form that requires the user to specify dimensions for an item they are ordering.
A list must show for standard or popular dimensions. Originally this would happen when the field is selected, the list would show below. Maybe a "search" icon on the right side would be more fitting?
Having single fields such as
Length: 42.12 Width: 12.3 Height: 4.42
could look nice with some styling, but having a drop down appear underneath these fields seems a bit odd.
Alternative would be a single field like so:
Dimensions (in.) : 42.12 x 12.3 x 4.42
The separator makes this painful to look at. Maybe styling the text so the separator is very faint would be good? For validation I could prevent the user from typing any non-numeric or decimal point character, and when a space is hit it automatically adds the separator, but this might be confusing.
