That is not opaque, the reason is : the level of SSelect is lower than other components
you need to add z property to control the level

Example

SSelect {
// z is larger than SButton's z
    z: 100;
    y: 100px;
    font-weight: 700;
    is-show: true;
    theme: Error;
    card-width: 300px;
    options: [
      {label:"Shangai",value:"s01"},
      {label:"Los Angeles",value:"l02"},
      {label:"New York",value:"n03"},
      {label:"Hong Kong",value:"h04"},
    ];
    changed(index,item)=>{
      t.index = index;
      t.label = item.label;
      t.value = item.value;
      self.close();
    }
  }
  SButton {
    z: 10;
    text: "up";
  }

If z is larger, the level of the component will be higher
