wow - thanks everyone for your responses. I didn't expect so many so
fast. all the responses were interesting.
I guess my explanation was not very clear. I'll try again.
I have a long list of items (list A) each of which can use a short
list of items (list B), either singularly or more than one. the
problem is assigning one or more items in list B to one or more items
in list A. and then you have to account for going back and selecting
multiple items in list A and indicating which items in list B belong
to them even when they may have different assignments.
I am now leaning toward displaying all the items in list B for each
item in list A with checkboxes even though there is a lot of
redundancy in the display, like this, because at least there is no
confusion about which items in list B belong to list A and it is still
relatively quick to select list B items even though you can't make
multiple assignments at once.
Item A1
[checkbox] item B1
[checkbox] item B2
[checkbox] item B3
Item A2
[checkbox] item B1
[checkbox] item B2
[checkbox] item B3
Item A3
[checkbox] item B1
[checkbox] item B2
[checkbox] item B3
Item A4
[checkbox] item B1
[checkbox] item B2
[checkbox] item B3
...
2nd runner up was a checkbox display for the items in list B that
would show [-] when incompatible selections were made (selected for
some) rather than [x] (selected for all), or [ ] (selected for none).
Anyone who has read this far gets a gold star!
Anyway, if anyone has any OTHER suggestions, let me know...
thanks again to everyone who responded so far.
Michael
