If you want to build your own dashboard, you should refer to nextjs layouts. They might be helpful for you. If you don’t want to build your own dashboard, please clarify your question

actually creating dashbaord from scratch take alot of time

i wonder if their any existing one which has best use case so i can start for production

yea, I think the content in each route depends on you, so I recommend use to get a default sidebar (https://flowbite.com/docs/components/sidebar/) and after that design your individual cards
