Create a Conga Batch List View Button
This is a Javascript button and Javascript is not supported in Salesforce Lightning. This feature is not supported in the Salesforce Lightning user experience. For a Lightning-ready Visualforce button, see Create a Conga Batch List View Button (Lightning Experience)
Setting up a List View button to launch Conga Batch is easy. You create a button on the Master Object, paste the code from the Conga Batch Sample List View button, adjust the code to your needs, and place the button on the object’s Search Layout.
Due to their complicated nature, the integration of Conga with JavaScript, Visualforce, and Apex (or other programming languages) is outside the scope of support available from the Technical Customer Success team.
