Ps: I also added the filter reset button to our todo list.
Reset button I think I can do this way: create Custom field "All" and set it for every item. So, then in filter I'll have All, Test 1, Test 2, Test 3... options. And click on All will show all items.
but how to mark selected option in filter I can't understand.
