Hi Team,

I have a dialog where i am allowing authors to input data via multifield. Authors can add n numbers of multifield as per requirements.

Now my problem is, when authors open the dialog of my component, i want atleast one multifield to be available if there is no data available.

Please help.

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");

Hi,

Thanks a lot for your reply but i just want a validation where i can check if I have any mulitfield already in the dialog then do nothing and if the dialof don't have any multifield data, then show one multifield, so that author understands what data to fill in the box and disable delete button in case there is only one multifield available in the dialog box.

Any solution around this?

This is not something which is possible with OOTB multiifled. You may have to do a workaround by customizing it .
