try this: ``` input[type="range"].multirange { -webkit-appearance: none; } input[type="range"].multirange.middle, input[type="range"].multirange.original{ background: linear-gradient(to bottom, rgba(255,255,255,0) 0%,rgba(245,245,245,0) 37%,rgba(245,245,245,1) 38%,rgba(242,242,242,1) 50%,rgba(245,245,245,1) 62%,rgba(245,245,245,0) 63%,rgba(255,255,255,0) 100%); } ```

workaround it with the following ``` let parentElements = this.drop.querySelectorAll("li.grouped-option"); if(parentElements){ Array.prototype.slice.call(parentElements).forEach(function (x) { self.checkUncheckFromChild(x.nextSibling); }); } ``` before line 1288 ``` self.title.textContent = selectedTexts; self.privateSendChange(); ```
