Re: Multiple Select Widget

Thanks. These are good solutions.

I was considering having a:


 1.  combo box with the full set of options
 2.  a link that says "select more than one"
 3.  on click a second combo box with the same options (minus any already
selected) appears

(1) many times such tasks are better supported with the "Add/Remove"
idiom (two side-by-side lists, with arrows to move each lists'
selection to the other list)*.  Add/Remove can sometimes be
advantageous because the real selection is more persistent and less
fragile than typical widget selections-- for example, in multiselect
List Boxes, a single accidental click can clobber a carefully
assembled multiple selection.

(2) many times such tasks are better supported with a "Shopping Cart"
idiom (pick items from a list and put them into a cart).  Shopping
Carts similarly have the advantage of a relatively persistent selection.

Shopping Carts work well when your lists are so large as to require
other navigational machinery such as Browsing, Search, Filters,
Sorting, etc. for the user to easily and successfully find the items s/
he needs to select.


Some tasks are faster and more reliably done by selecting-all (or
selecting many) and then selectively REMOVING items from the
selection.  Consider that.
