Is there any way to copy the data like copy to clipboard that comes out of box?

Hello,
 
Thank you for your question.
 
We kindly recommend the following approach:
 
1) Specify the customizeContextMenu parameter to customize the context menu:

customizeContextMenu: customizeFlexmonsterContextMenu

2) Define the function responsible for the customization. For example, the copy option can be added to the context menu in the following way:

function customizeFlexmonsterContextMenu(items, data, viewType) {
  items.push({
    label: "Copy",
    handler: function() {
       console.log(">>>>", data);
       //extract needed information and implement copy
    }
  });
  return items;
}

Here is a JSFiddle example for illustration.
 
2) In the handler function, you can provide your implementation for copying the needed information.
 
Please let us know if this works for you.
 
Best Regards,

Hello,

If you need to copy data like a table structure I can recommend you to try export data to CSV.
Does it meet your needs?
