 - Name of filters should be set on the list's parent element using data attribute with the syntax `data-filter-names=“filtername1 filtername2”`.
 - List items that match a filter need a data attribute with syntax `data-filter-filtername=“filtervalue1”`. If an item has multiple values for a certain filter separate them by space: `data-filter-filtername=“filtervalue1 filtervalue2”`.
