"Expanded view" button should be collapse all option group for second click

[Sohorev]

For first click this button expand all option group - it's cool
But for second click this button should be collapse all option group. Or implement other button "Collapse view".
Thank you

there is a view button (the eye icon) is served as a way to collapse to those selected only. if nothing selected, it will collapse all groups.
