 Here, the search filter and filter group containing three drop-down filters are placed in a toggle group that collapsed when the screen shrinks to mobile size. The two action buttons are part of an overflow menu that collapses to a single kabob menu. The bulk selector and sort icon button are implemented as toolbar items that remain visible at all breakpoints.
