I'm trying to figure out the best way to display a list of USA States where multiple items, or all, can be selected.
The obvious UI element that exists for this sort of thing is the field where a long list of items can be shown and a user can select multiple from this list providing they know the key combinations to do so (holding control and click etc)
Checkboxes & List
Another solution I thought of was simply outputting all the States into a list (alphabetically order) which checkboxes next to the names. This is a little more intuitive for the user but takes up a large amount of space.
I wonder if any of my ideas are the correct experience for the user or whether a better solution exists.
