# 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.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.variant3d.com/variant-js-sdk/setting-mesh-options.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
