 * To hide and show the filters, we wrap the filters and the content in a view that is bigger than its parent
 * container, that has its overflow hidden. By default the filters are not shown, and gets translated out of the view.
 * With JavaScript we toggle the filters in and out of the view, by translating the X position of the view.
 *
 * This gives a smoother transition than working with changes in the width or the margin.
