# URL control options This section lists project options which can be set via URL query string keys. For example, add `?tt=cr` to the end of a project link to set tree type to circular: . Multiple options can be combined using ampersand character (`&`). For example, add `?tt=cr&tl=0` to the end of a project link to set tree type to circular and hide tree labels. **Filter URL Options** | Option | Description | Default value | Accepted values | | ------ | ---------------------- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------ | | `fb` | Metadata block columns | | Sets the initial columns displayed as metadata blocks on the tree.
