This feature is available from OpenKM version 7.1.38 and upper.

The following sample demonstrates how to create a new custom action in the KCenter.

Sample based in a JSP

Step 1 - Create a sample JSP file

Create the following sample JSP file and copy it to the webapps/openkm folder with name test.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ page isErrorPage="true" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>

<html>
<head>
  <script type="text/javascript" src="<%=request.getContextPath() %>/kcenter/api/common.js"></script>
  <script type="text/javascript" src="<%=request.getContextPath() %>/kcenter/api/modal.js"></script>
</head>
<body>
  <h1>Quick sample about how to create a custom action in the KCenter</h1>

  <p><b>UserId:</b> <%=request.getParameter("userId")%></p>
  <p><b>Uuid:</b> <%=request.getParameter("uuid")%></p>
  <p><b>Encrypted token:</b> <%=request.getParameter("token")%></p>

  <button onclick="_closeCustomFeatureModal()">Close popup</button>
</body>
</html>

Step 2 - Register the custom action

Create a new custom action with these values. More information at Custom actions.

Field	Value
Name	test
Label	Label test
Icon	mdi-copy-all
Description
Document	false
Folder	true
Record	false
Mail	false
URL	../test.jsp Another option: http://localhost:8080/openkm/test.jsp
Action	popup-wizard
Location	node-toolbar
Width	50%
Height	50%
Show close	true

Step 3 - Enable the custom action in the profile

Go to Administration > Profiles
Edit a profile and enable the custom action in the Misc tab.

Step 4 - Check the feature

Refresh the KCenter UI
Select a folder in the browser view.
In the contextual menu or in the toolbar menu is shown a new menu option named "Extra"
