How do I render blocks of html dynamically using ReactJS?

Question

I'm struggling with being able to render html elements in my sidebar dynamically. Currently, this is only set up to receive a list of projects of at least 1 but up to 5, as well as 1-5 subprojects. The HTML is hardcoded, and I was wondering if there is a way to just reuse the same block of HTML for each item in the project list.

import React, { useContext, useEffect } from 'react'
import { Link } from 'react-router-dom'
import { DashboardContext } from '../dashboardContext/DashboardContext'
import './sidebar.css'
import Accordion from 'react-bootstrap/Accordion'
import Card from 'react-bootstrap/Card'
import './homeicon.png'

function Sidebar() {
    const [view, setView] = useContext(DashboardContext)

    var host = "http://localhost:3000/"
    var config = view.configFile
    var itemToFetch = host + config
    const data = view.configInput

    useEffect(() => {
        async function fetchData() {
            const res = await fetch(itemToFetch);
            res
                .json()
                .then(res => setConfigData(res));
        }
        fetchData();
        // eslint-disable-next-line react-hooks/exhaustive-deps,
    }, [view.configFile]); //fetchData when view.configFile changes

    //have to make separate setter functions because otherwise the whole view gets overwritten (i.e., with "undefined")
    const setProject = (name) => {
        setView({ ...view, name: name });
    }

    const setConfigData = (data) => {
        setView({ ...view, configInput: data })

    }

    if (data == null) {
        return (null)
    }

    // NEEDS HELP
    //currently this is only set up to receive project lists of at least 1 but up to 5
    //the number of subprojects can be up to 6 (the compiler doesn't complain about having the expected number of subprojects if it's below that)
    else if (data != null) {
        return (
