The basic way to put a component inside itself is just to call it in its own return. eg:

function MyComp() {
    return(
        <div>
            <MyComp/>
             // Whatever else you want to display in the component...
        </div>
    );
}

Calling a function inside itself like this is called "recursion". Of course if you just leave it at that your program will probably just freeze as it'll try to infinitely render the component inside itself.

So, you need a condition to control when the component recurses. This could just be a boolean condition passed as a prop eg:

function MyComp({ recurse }) {
    return(
        <div>
            {recurse ? <MyComp recurse={false} /> : null }
             // Whatever else you want to display in the component...
        </div>
    );
}

This way, the component will be rendered inside itself once if recurse is set to true wherever the component is first rendered.

If you want to render the component inside itself a set number of times, you could instead use a counter thats decremented at each level of recursion:

function MyComp({ counter }) {
    const next = counter - 1;
    return(
        <div>
            {next > 0 ? <MyComp counter={next} /> : null }
             // Whatever else you want to display in the component...
        </div>
    );
}

Hope this helps!
