Hi Rakesh,
I am assuming thag you want to know if itsi possible to remove the Filter section from a custom object's list view page, right? If my understanding is correct, then I would like to confirm you that it's NOT possible.
That list page is a page that is designed for all the objects, as soon you create it. You can keep the List Filter section collapsed or expanded based on your requirement, but you cannot remove it, neither can you hide it. Hope that answers your question.
Thanks,
Abhisek Dhar
