# Setting Mesh Options

### Meshes

Each mesh option object looks like this:

```javascript
{
      tag: 'CHAIR',
      enabled: true   
},
```

The `meshes`array of the `options` object should contain the tags and enabled states of meshes you wish to include in your variant:

```javascript
var data = {
    productCode: 'SKU001'
    options: {    
        meshes : [
            {
                tag: 'CHAIR',
                enabled: true   
            },
            {
                tag: 'FOOTSTOOL',
                enabled: true
            }            
        ]
    }
};

Variant.launchQuicklook(data);
```

{% hint style="info" %}
You should only include each tag once in the meshes array
{% endhint %}

By default all tagged meshes are disabled, so setting `enabled:false` is optional.

### Mesh Groups

Mesh tags in the file can also apply to groups of meshes (toggling on/off a parent node that contains multiple child meshes in the hierarchy).

When toggling meshes and mesh groups on or off, the parent item in the 3D model's hierarchy will take precedence. 

For example if `GROUP` contains `MESH` and you set `GROUP` to be disabled, then `MESH` will be always be disabled, even if explicitly set to enabled. This behaviour mirrors what you would expect in a 3D editor or game engine.
