+CopyInput Bootstrap component contains input with a label, predefined sizes, and
+structure for use in ForisForm and the "Copy" button (copy to clipboard). It can
+be used with `readOnly` and `disabled` parameters, please see an example.
+
+All additional `props` are passed to the `<input type="text">` HTML component.
+
+```js
+import React, { useState } from "react";
+const [value, setValue] = useState("Text to appear in clipboard.");

+<CopyInput
+    label="Copy me"
+    value={value}
