The JSModel.java path need to be updated to /etc.clientlibs proxy as all new client libs reside in /apps, all categories and dependencies are proxy to etc

$(document).on("select", ".cq-dialog-dropdown-showhide-multi", function(e) {

Should be:

$(document).on("selected", ".cq-dialog-dropdown-showhide-multi", function(e) {

That solved in my repo

Hi Arun,

I am using a multifiled with dropdown selection to populate feilds based on the selection, I have added the js which is suggested [here](https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/aem6-4-multifield-with-show-hide-dropdown-changing-all-the-items/qaq-p/237275/comment-id/39523#M39523
videoList-0.1.zip
), now the dialog is retaining the values but at the node level its adding an extra empty node. When I try to add another item to the existing list its adding the entire set double time. I have attached the complete component below in the AEM package but when I try to author the component its adding an empty item for each filed. Pls see the below attachment.

getting this exception : org.apache.commons.mail.EmailException: Invalid message supplied
