Preload data with nested and multiple values
Syntax
This example shows an concept, how to handle the VisualData form parameter 'preload-data' with nested and multiple values. This makes it possible to generate dynamical forms.
Notice the placeholder $ and the value separator @@@@. The value separator can be set in VisualData queries, see below.
|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 +

Workflow example
Step 1: Define one or more statistical class sets
Step 2: Attach class sets to a page
Step 3: Add datasets to a page
{{#visualdataform: Dataset
|title = {{int:webmo-add-dataset}}
|action = create
|return-page = {{FULLPAGENAME}}
|view = popup
|popup-size = larger
|css-class = form-dataset
|pagename-formula = <unique title>
|edit-freetext = false
|edit-categories = false
|edit-content-model = false
|edit-target-slot = false
|target-slot = main
|default-content-model = json
|preload-data?belongs to = {{PAGEID}}
|preload-data?classes/$/class name = {{#visualdataprint:{{#visualdataprint:{{PAGEID}}|?classes|schema = Indicator classes|format = raw}}|?class names|schema = Data classes|format = raw|values-separator = @@@@}}
|preload-data?classes/$/sub-classes/$/sub-class name = {{#visualdataprint:{{#visualdataprint:{{PAGEID}}|?sub-classes|schema = Indicator classes|format = raw}}|?class names|schema = Data classes|format = raw|values-separator = @@@@}}
|preload-data?classes/$/sub-classes/$/sub-sub-classes/$/sub-sub-class name = {{#visualdataprint:{{#visualdataprint:{{PAGEID}}|?sub-sub-classes|schema = Indicator classes|format = raw}}|?class names|schema = Data classes|format = raw|values-separator = @@@@}}
}}
