Re: Multiple Select Widget

That is really something! Not sure if it isn't overly complex, but
intriguing.

At the link above, try "more options" for the "Subject Terms" -- click on a
few options and look at the query builder at the top of the modal window.

I like the fact that it gives feedback on the items selected and offers the
ability to include and exclude selected topics.

(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.
