Hi,
Assuming that you're using sling:resourceType as "granite/ui/components/foundation/form/fieldset", please use the following JS logic (nested-multifield.js here) that creates and fills the nested multifield with one multifield item open by default on dialog load. The highlighted lines of code in the below js file is responsible for populating one multifield item open by default if there is no data available.
nested-multifield.js:
(function ($, $document) {
var EAEM_NESTED = "eaem-nested",
DATA_EAEM_NESTED = "data-" + EAEM_NESTED,
CFFW = ".coral-Form-fieldwrapper",
NODE_STORE = "NODE_STORE";
if(CUI.Multifield.eaemNMFExtended){
return;
}
CUI.Multifield.eaemNMFExtended = true;
function isNodeStoreMultifield(type) {
return (type === NODE_STORE);
}
function isSelectOne($field) {
return !_.isEmpty($field) && ($field.prop("type") === "select-one");
}
function setSelectOne($field, value) {
var select = $field.closest(".coral-Select").data("select");
if (select) {
select.setValue(value);
}
}
function isCheckbox($field) {
return !_.isEmpty($field) && ($field.prop("type") === "checkbox");
}
function setCheckBox($field, value) {
$field.prop("checked", $field.attr("value") === value);
}
function isDateField($field) {
return !_.isEmpty($field) && $field.parent().hasClass("coral-DatePicker");
}
function setDateField($field, value) {
var date = moment(new Date(value)),
$parent = $field.parent();
$parent.find("input.coral-Textfield").val(date.format($parent.data("displayed-format")));
$field.val(date.format($parent.data("stored-format")));
}
