Multiple slicer dependency

Ok, so, my proposition for you is to use bookmarks:

1. Add your Date slicer to the page and go to View/Bookmarks / Add . Make sure no selection is done to the slicer and create the bookmark "Month" with the following settings (data checked)

2. Add another bookmark called "Hebdomadaire" this time make sure the Data is not checked

3. Insert/Buttons/Navigator/Bookmark Navigator with FORMAT grid layout vertical

Now every time you click Hebdomadaire you can select a date and the value in your card will adapt but when you select month, the filter will be cleared.

If it answers you query, please mark my reply as the solution
