+> **Note:** `x` in the above example can be replaced with any valid icon name. See the complete list of icon names at [feathericons.com](https://feathericons.com). Icons with multi-word names (e.g. `arrow-right`) **cannot** be accessed using dot notation (e.g. `feather.icons.x`). Instead, use bracket notation (e.g. `feather.icons['arrow-right']`).
