This is a jQuery plugin for enabling People Picker control on SharePoint 2013 pages.
- Download the script files and upload it to a location (either in style library) or 15 hive on your SharePoint server
- Provide a reference to the jQuery library before we use the plugin
- Provide a reference to the sppeoplepicker.min,js on the page
- Create a div element with an id attribute
- call the spPeoplePicker() on the div element in document.ready function
I also uploaded the original JS file. It is open and you can change it as per your requirement.
