Thanks Mr Gravitonian,
I've made some research but I didn't get a consistance response until now.
Recently, I've found that I should use the copy-move-to.js script in my Freemarker file of my webscript that generate the list of documents(regarding to 5.0 version of Alfresco). I think I should add the following line in the top of my ftl file :
<@script type="text/javascript" src="${page.url.context}/res/modules/documentlibrary/copy-move-to.js"></@script>
But, until now, I didn't get any example in which I could focus to understand how to use it.
Have anyone any idea to help me, please?
