I am a new SharePoint 2010 user. I have a situation where I need to add templates to a sharepoint library, so when a user selects "New Document" a list of templates displays. Multiple templates have been developed for each type of document-example:There is an Announcement template available in MSWord, Outlook, and PowerPoint. Users will pick their template based upon the best delivery method. There are 12 other types of content/documents that have multiple templates, so the list is too long to display as a straight dropdown from "New Document". Is there a way to have the different templates display when the user hovers over or clicks on the template? Example: User clicks or hovers over Announcement and Outlook, MSWord, and PowerPoint display?
As far as I know, it is not possible to do this out-of-the-box. You have to develop a solution for this.
But there is already an open source project called Template Hub for SharePoint on codeplex existing for this purpose. It is well documented and available for SharePoint 2010 and SharePoint 2013.
Have a look at this. Maybe this fits your requirements.
