# VariantFeatureWidget Auto-generated @jbrowse/mobx-state-tree API for the current JBrowse release — see [pluggable elements](https://jbrowse.org/jb2-staging/docs/developer_guide/) for concepts. Provided by the `variants` plugin. [View source](https://github.com/GMOD/jbrowse-components/blob/main/plugins/variants/src/VariantFeatureWidget/stateModelFactory.ts). Feature-details widget for a VCF variant, extending the base feature widget with variant-specific fields such as genotypes and INFO. Members a composed model contributes are listed here too, so these tables are the whole surface. ## Properties | Member | Description | Defined by | | --- | --- | --- | | **type**
