Hi,

try this,

Create one static node name like 'NodeA'

Create one Node using the following code. Inside the DoInit() method

Private<ViewName>.INodeAElement ele = wdContext.createNodeAElement();

wdContext.nodeNodeA().addElement(ele);

IWDNodeInfo multipleinfo = wdContext.nodeNodeA().getNodeInfo();

IWDNodeInfo multiplenode = multipleinfo.addChild("MultiNode" , null, true, false, true, true, false, true, null, null, null);

multiplenode.addAttribute("roles", "ddic:com.sap.dictionary.string");

Step 2:

Assign values for Dropdown

IWDNode node1 = wdContext.nodeNodeA().getChildNode("MultiNode", IWDNode.NO_SELECTION);

IWDNodeElement elem1;

//determine the number of entries in dropdown say size

for(int s=0;s<size;s++){

elem1 = node1.createElement();

elem1.setAttributeValue("roles",assign the values you want to list);

node1.addElement(elem1);

}

Step 3:

Inside Domodifyview create IWDDropDownByIndex UI Element and Bind it.

IWDDropDownByIndex dropDownList = (IWDDropDownByIndex)view.createElement(IWDDropDownByIndex.class, "drop");

IWDAttributeInfo info = wdContext.getNodeInfo().getChild("NodeA").getChild("MultiNode").getAttribute("roles");

dropDownList.bindTexts(info);
