How to add a classname/id to React-Bootstrap Component?

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

The first way is to use props:

<Row id = "someRandomID">

Then in the definition, you may use:

const Row = props  => {
    <div id = {props.id}> something </div>
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.
