I am just starting my 2nd project and can’t get past the first line. I am using standard BS-4 collapsible nabar which views well in other web pages I have designed previously. On these pages I used code copied almost directly from the Bootstrap site, with Bootstrap CDN copied from their page https://v4-alpha.getbootstrap.com/ .
However in Code pen, with BS-4 Css and Bootstrap-Js loaded in the “Pens” view the navbar appears only as the collapsed button (regardless of screen width) and the button just flickers when clicked. If I remove the collapsible button, the list items just stack down the page.
I have tried adding the Bootstrap CDN copied from their page at the bottom of the HTML section of the “Pen”; but this failed to solve the problem.
Do you think the JS I loaded in the (free account) code pen is the problem? How should I load the JS into Code Pen (Pens view)? Or should I just go back to BS3 version? Or any other suggestions.
