how to remove a customDataSource? for example i have two dataSources, like this below.

```auto
var dataSource1 = new Cesium.CustomDataSource('myData1');
var dataSource2 = new Cesium.CustomDataSource('myData2');

var entity1 = dataSource1.entities.add({
   position : Cesium.Cartesian3.fromDegrees(1, 2, 0),
   billboard : {
       image : 'image1.png'
   }
});

var entity2 = dataSource2.entities.add({
   position : Cesium.Cartesian3.fromDegrees(1, 2, 0),
   billboard : {
       image : 'image2.png'
   }
});

viewer.dataSources.add(dataSource1);
viewer.dataSources.add(dataSource2);

```

what should i do to remove only the dataSource2 ?

Hi @Ahyar,

Thank you for the thoughtful question! I recommend using the `remove` method of `DataSourceCollection` to remove `dataSource2`. Here is the documentation for `remove`:

[https://cesium.com/learn/cesiumjs/ref-doc/DataSourceCollection.html#remove](https://cesium.com/learn/cesiumjs/ref-doc/DataSourceCollection.html#remove)

This should help you get started. Please let me know if you have any other questions or concerns.

Best,  
Sam

Hi @Ahyar,

Thank you for sharing this with me. It would be helpful if you could provide a more complete code example. For instance, a [sandcastle demo](https://sandcastle.cesium.com/) that showcases the error would be very helpful. I suspect that this issue stems from the variable `dataTitik`.

Best,  
Sam
