Syntax[edit | edit source]
This example shows a concept, how to handle the VisualData form parameter 'preload-data' with nested and multiple values. This makes it possible to generate dynamical forms, e.g. to collect data differentiated by district, gender and age categories:
...
|preload-data?classes/$/class name = District 1@@@@District 2@@@@District 3
|preload-data?classes/$/sub-classes/$/sub-class name = female@@@@male@@@@diverse
|preload-data?classes/$/sub-classes/$/sub-sub-classes/$/sub-sub-class name = 0 - 14@@@@15 - 29@@@@30 - 44@@@@45 - 59@@@@60 +
...
Notice the placeholder $ and the value separator @@@@. The value separator can be set in VisualData queries, see below.
Required json-diff library is not installed. Run composer in the extension folder to enable preload-data
