Please use the following code example to insert the drop down list in the document. The input and output documents are attached.
Docs.zip (21.7 KB)

var doc = new Document(MyDir + "input.docx");

StructuredDocumentTag sdt = new StructuredDocumentTag(doc, SdtType.DropDownList, MarkupLevel.Block);
sdt.ListItems.Add(new SdtListItem("Item 1"));
sdt.ListItems.Add(new SdtListItem("Item 2"));
sdt.ListItems.Add(new SdtListItem("Item 3"));

Table table = (Table)doc.GetChild(NodeType.Table, 0, true);
table.FirstRow.FirstCell.AppendChild(sdt); 
doc.Save(MyDir + "out.docx");
