Fix:

    When I click on "new article" icon, and on the cross after, the filter icon is no more visible.
    When I change the size of my browser window, the filter appears but I didn't click on the icon
    Bug: can't click on pagination > 1
    display bug: when we load homepage, we see quickly the filter form
    new entry form: when we click on the field, the history of the field is at the left of the screen, not below the field (see screenshot)
