How can i get the filters above the product grid like in the screenshot?
Well you can't have it on the product grid as far as I know because this grid is rendered using a
ui_component. These kind of filters are there when we create a grid using blocks. You need to remove this grid in your
custom module and follow the link- https://jutesenthil.wordpress.com/2016/04/11/how-to-create-admin-grid-in-magento2-part5/ to make this kind of grid.
