If i have a multi-select widget inside a repeat loop, is there a way to
prevent a user from selecting an item that has been previously selected?
The use case scenario : a multi-select where a user may not select an item
more than once.

I've been mucking with the pyxform source code and discovered something
interesting - this is already supported. There are caveats though: it
doesn't follow xlsform convention: (1) the "names" couldn't be integers and
(2) labels are handled differently - "%(label)s" versus the conventional
${variable} notation.
*survey*
type name label:English appearance hint
begin_group g_farm_item
table-list Drop “table-list”. Incompatible with begin_loop.
begin_loop farm_items
select_one yes_no usage Do you use %(label)s ?
select_one yes_no ownership Do you own %(label)s ?
end_loop
end_group
choices
list name name label:English
yes_no 1 Yes
yes_no 2 No
farm_items fi_1 Beast of burden
Normally, my names are integer values (1, 2, etc.) but ODK complains if I
do that, hence the “fi_” prefix.
farm_items fi_2 Plow
farm_items fi_3 Harrow
farm_items fi_4 Mower
farm_items fi_5 Thresher
farm_items fi_6 Insecticide
farm_items fi_7 Farm tractor
farm_items fi_8 Hand tractor
farm_items fi_9 Mechanical dryer
farm_items fi_10 Harvester
farm_items fi_11 Granary / Warehouse / Silo
farm_items fi_12 Farm shed
farm_items fi_13 Irrigation pump
Is it safe to deploy a form using this? (By the way, there's a copy here:
http://formhub.org/n1kn0k/forms/list_loop)
Best,
Nik

The loop feature of pyxform has been voted for removal by the dev team, and
the code hasn't been maintained for a little while now. So I would use with
caution (and make sure that you can run a version of pyxform that does
loops locally... see https://github.com/modilabs/pyxform/tags for a list;
looks like the current version works, and before that, you'll have to do
trial and error. (PS. try the loop outside the group to see if table-list
remains supported).
I don't quite clearly see how it solves your original problem though...
isn't the main technique you have used just changing the multi-select to a
series of select ones so that you can go through them one by one?
cheers,

The
loop had nothing to do with the original post.
Anyway, are you referring to the formhub dev team or the pyxform dev team?
So far, I can see how useful this loop is.
