@ -113,12 +113,29 @@ def massive_bootstrap_form(form, mbf_fields, *args, **kwargs):
A dict of list of ids that the values depends on. The engine
and the typeahead properties are recalculated and reapplied.
Example :
'addition' : {
'update_on' : {
'field_A' : [ 'id0', 'id1', ... ] ,
'field_B' : ... ,
...
}
gen_select (optional)
A dict of boolean telling if the form should either generate
the normal select (set to true) and then use it to generate
the possible choices and then remove it or either (set to
false) generate the choices variable in this tag and do not
send any select.
Sending the select before can be usefull to permit the use
without any JS enabled but it will execute more code locally
for the client so the loading might be slower.
If not specified, this variable is set to true for each field
Example :
'gen_select' : {
'field_A': True ,
'field_B': ... ,
...
}
See boostrap_form_ for other arguments
