Hi @SagarVirani
You want to build a custom bundle from all product available in store.
For this you have to create a custom product page.
You can provide a product search box where user will able to search the product selected product will be added into the cart.
Add their preview will be visible below of search bar with cross button.
When limit reaches search box will be hide. If user delete any product search box will be visible again to select.
But again this whole thing will take lots of time to dev.
