Selecting multiple values and applying them to a DetailsList

Hi
I am trying to filter a DetailsList by getting the values from a Select.

I am able to filter the DetailsList by using hard-coded text but I'd like to be able to loop through the selected options and check for those.

Thanks
S

private handleChange = (selectedOptions) => {

  this.setState({

    selectedOptions,
    Items: Text ? this._allItems.filter(i => i.Category.toLowerCase().indexOf("choice 1") > -1) : this._allItems

  });


selectedOptions.forEach(function (value) {
  console.log(value);
  console.log(value.value);
  console.log(value.label);
}); 

}
