I built an online catalogue for the store I work at. No you cannot order from it. Its not its intended purpose. I am after making close to a hundred html pages now for the store. My issue is if I edit one item in the nav menu I have to copy and paste it into all the html files. Is there a way around this. here is the html for the nav.
<nav class="navbar navbar-expand-lg navbar-dark nbc">
