# FieldDependenceMultiLevel

Set `FieldDependenceMultiLevel` to `True` to use a hierarchical structure to display FieldDependence result values for multiple fields.

Note: Setting `FieldDependenceMultiLevel` to `True` automatically sets FieldDependence to `True`.

By default, the results return in a flat structure that lists the value of the first field from the FieldName parameter in the `<autn:value>` tag, followed by `<autn:subvalue>` tags that list the values of subsequent fields. When you set `FieldDependenceMultiLevel` to `True`, the values are listed in a hierarchy, with the first field at the top, and subsequent fields underneath it. For example:

    <autn:field>
       <autn:name>Field1</autn:name>
       <autn:name>Field2</autn:name>
    </autn:field>
    <autn:values>
       <autn:field value="CABERNET" count="3">
          <autn:field value="MERLOT" count="2" />
          <autn:field value="MALBEC" count="1" />
       </autn:field>
    </autn:values>

The `count` attribute shows how many instances of the value occur in the result documents. For the first field, the count is the total number of times that the value occurs. For the subsequent fields in the hierarchy, the count shows how many times that value occurs with the corresponding value of the previous fields. The previous example represents two occurrences of the set `Field1=CABERNET, Field2=MERLOT`, and one occurrence of the set `Field1=CABERNET, Field2=MALBEC`.

If you set ValueDetails to `True` when `FieldDependenceMultiLevel` is set to `True`, IDOL Server prints the details for the last FieldName in the hierarchy, in the context of the previous fields.
