17.16.4 ddList (Drop-Down List Form Field Properties)

This element specifies a set of properties which shall be associated with the parent FORMDROPDOWN drop-down list form field (§17.16.5.21) within the document.

If the parent form field is not a drop-down list (i.e. its field code does not have a value of FORMDROPDOWN), then these properties can be ignored.

[Example: Consider the following WordprocessingML fragment for the properties of a drop-down list form field:

<w:ffData>
<w:ddList>
<w:listEntry w:val="One" />
<w:listEntry w:val="Two" />
<w:listEntry w:val="Three" />
</w:ddList>
</w:ffData>

The ddList element specifies that it contains a set of properties for the parent drop-down list form field. In this case, these properties specify that the drop-down list must contain three entries of One, Two, and Three via the listEntry elements (§17.16.25). end example]
