deform_widget_jquery_option_tree 0.2.1

jQuery Option Tree widget for deform

Latest Version: Unknown

This package makes jQuery Option Tree available as a deform form library widget. jQuery Option Tree converts a JSON option tree into dynamically created <select> elements allowing you to choose one nested option from the tree.

Currently only one feature for a very specific use case is implemented, hierarchical browsing from a data structure like this:

key     value
---     -----
1       Option 1
11      Suboption 1.1
111     Subsubption 1.1.1
112     Subsubption 1.1.2
12      Suboption 1.2
2       Option 2
21      Suboption 2.1
22      Suboption 2.2
3       Option 3

This is suitable for hierarchical selections from standards like ISCO08 or NACE Rev. 2

The implementation currently requires the data to be exposed by a REST service with 2 endpoints that are reachable via a common base URL (the json_url option of the widget):

  • json_url has to return the top level key/value pairs
  • json_url with the GET parameter ìd has to return the child elements for the given id.
  • json_url + '/<id>/lineage' has to return the lineage of IDs from root to leaf for the given <id>.

Examples:

json_url = '/api/classifications/nace_rev2'

# GET call to '/api/classifications/nace_rev2'
# has to return a structure like this:
{
    A: "LAND- UND FORSTWIRTSCHAFT, FISCHEREI",
    B: "BERGBAU UND GEWINNUNG VON STEINEN UND ERDEN",
    C: "VERARBEITENDES GEWERBE/HERSTELLUNG VON WAREN"
}

# GET call to '/api/classifications/nace_rev2?id=A'
# has to return a structure like this:
{
    A01: "Landwirtschaft, Jagd und damit verbundene Tätigkeiten",
    A02: "Forstwirtschaft und Holzeinschlag",
    A03: "Fischerei und Aquakultur"
}

# GET call to '/api/classifications/nace_rev2/Q8690/lineage'
# has to return a structure like this:
["Q", "Q86", "Q869", "Q8690"]

See the included demo application for details.
