+# No experimental SelectPanel
+
+## Rule Details
+
+This rule enforces the usage of specific imports from `@primer/react/experimental`.
+
+👎 Examples of **incorrect** code for this rule
+
+```jsx
+import {SelectPanel} from '@primer/react/experimental'
+
+function ExampleComponent() {
+  return <SelectPanel />
+}
+```
+
+👍 Examples of **correct** code for this rule:
+
+You can satisfy the rule by either converting to the non-experimental version:
+
+```jsx
+import {SelectPane} from '@primer/react'
+
+function ExampleComponent() {
+  return <SelectPanel />
+}
+```
+
+Or by removing usage of the component.
