Sure Rahul,
Thanks for it

Hey @Rahul-RB ,

Can you Please help me in https://codesandbox.io/s/thirsty-joliot-pjhkd?file=/src/AddAndDeleteTab.js

actually, I want to add a Whiteboard in those tabs..
Now, I'm stuck at one point..

When I draw something in the whiteboard and switch the tabs, then my tabpanel re-renders, but I don't want to do so. I want to avoid the re-render of tabpanel.

And my second issue is, Suppose I draw something on WhiteBoard1 and I close that tab 1.. then, that content will be shifted to the next tab, and shows as the content of tab 2..

Please help me in this..

Can the tabs be renamed?

hey @Rahul-RB do we have an example where there are contents to these tabs?
