Show colors squares in line

In the widget, under the Type dropdown, select Color instead of List.

i do this and dont work…

i solve the ploblem with this in custon css:

div .widget_layered_nav ul li {
    overflow: hidden;
    padding: 0px;
    width: auto;
}
.yith-wcan-label li, .yith-wcan-color li {
    display: inline-block;
}
.yith-wcan-label li, .yith-wcan-color li{
    display: inline-block;
}
