On this said page there are 4 filters, here is the current design of the drop-down filter. However if you were to select say 20 of the 40 would you be looking for a "Clear Filter" button? The cancel button just closes the dropdown and does not change the current selection or should that also clear selected filters?
I could add one in however what would the best order be? "Apply" "Clear Filter" "Cancel"?
This looks like a drop down select box, so having Cancel is a bit weird in this context anyway. I would expect to cancel by clicking the drop down arrow a second time, or clicking outside the menu.
In that case, you could use the space currently used as a cancel button as a clear selection button instead.
I would also swap the position of the Apply and Clear buttons, and make the clear a text button (text on a white background) instead of a full button, as it should not have equal presence as the Apply button.
Ideally your first option in a drop-down filter should be a Select All Option, on toggle on which you will select and unselect all filter values.
