Hi Lau,
Looks interesting I would implement it a bit different as a list of
dictionaries whose values are list of sub-options:
[ { 'Year1' : ['subject11','subject12'], 'Year2': [
'subject21','subject22','
subject23' ]}
The implementation on the server side would not be too hard, the frontend
code would be the hard part: coding the relationship of the metadata and
the related Javascript code to update the second list on changes to the
first one. The other problem would be accesability, I don't know how much
dynamic fields using Javascript would interfere with section 508
(https://www.section508.gov) and local Law 229 (www.oppi.gobierno.pr/*Ley229
*.pdf) both of which I try to follow as much as possible to keep to allow
governments to use Mayan.
It is an interesting feature I will keep it on the TODO list. Thanks!
