Examples

//find a group by its name
number qnaireRId = 17148177;
QuestionGroupRoot root = Questionnaire_getQuestionGroups(qnaireRId);
//QuestionGroupRoot root = new QuestionnaireTemplate(new Questionnaire(17148177).TemplateId).Groups;
QuestionGroupBranch branch = root.FindByName("G1");
print(branch.GroupName);//G1

//create new group branch 
Questionnaire qnaire = new Questionnaire (17148177);
QuestionnaireTemplate qt = new QuestionnaireTemplate (qnaire.TemplateId);
QuestionGroupBranch branch = new QuestionGroupBranch ("G1", qt);
QuestionGroupLeaf leaf = qt.Groups.FindByQuestion("Q1");
branch.SetChildGroups({leaf});
//add new group to group root
array groupRoot = qt.Groups.GetChildGroups();
groupRoot.Remove(leaf);
groupRoot.Add(branch);
qt.Groups.SetChildGroups(groupRoot);
qt.Save(true);

//add more goup leaf to a group branch
Questionnaire qnaire = new Questionnaire (17148177);

QuestionGroupBranch branch = qt.Groups.FindByName("G1");
QuestionGroupLeaf leaf = qt.Groups.FindByQuestion("Q2");
array childGroup = branch.GetChildGroups();
childGroup.Add(leaf);//add the leaf to branch
branch.SetChildGroups(childGroup);//reset group branch
array groupRoot = qt.Groups.GetChildGroups();
groupRoot.Remove(leaf);// remove the leaf from root
qt.Groups.SetChildGroups(groupRoot);// reset group root
