+Use the [codemod](https://github.com/mui/material-ui/tree/HEAD/packages/mui-codemod#select-classes) below to migrate the code as described in the following sections:
+
+```bash
+npx @mui/codemod@latest deprecations/select-classes <path>
+```
+
+### Composed CSS classes
+
+The CSS classes that composed the `icon` class and `variant` prop were removed.
+
+Here's how to migrate:

++ .MuiSelect-filled ~ .MuiSelect-icon
+- .MuiSelect-iconOutlined
++ .MuiSelect-outlined ~ .MuiSelect-icon
+- .MuiSelect-iconStandard
