Re: Multiple Select Widget

Thanks again. In this case the task is to choose multiple countries. The list
would be quite large. Of course you could group checkboxes by continents or
something.

Logical intuitive grouping of selections, as well as using Expand/Collapse
panels for subgroups to minimize complexity.  Expand/Collapse can be manual
(using button controls) or by mouse (eg, mouse over).  Depending on how often
the user is likely to change selections, the different methods suggested such
as Add/Remove can be more suitable.

(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.

 Hi Ryan,
Perhaps you could consider grouping related check boxes and adding a
"check all" option for each group.
