@group ROUTETOPA Polymer Core Elements
The `select-visualization-form-controllet` is a slider container of elements.
Pass to this component an array of components, a data url(CKAN api uri) and a string with one or multiple query in JsonPath format(separated by spaces) and it'll show a
slider with all components initialized with data and query attributes
### Code
