How to create a popup for login in woocommerce

Instead of a pop up, use a modal and perhaps you are using the term pop up generically.  

A stand alone modal library https://robinparisi.github.io/tingle/ but if you are using bootstrap there is a built in function. https://getbootstrap.com/docs/4.0/components/modal/.  Because you are using WP / Woocomemerce, you are better off using a plug in https://wordpress.org/plugins/tags/woocommerce-modal/

Either way, a modal is nothing more than a hidden div that is shown (popped up) after a click or some other type of event. Just before the modal is activated, you will inject your html form (or hard code it but that is more limiting). From there you will have a form you generated to initiate your log in.

Thank you, I was able to create login pop-up, however got one more question how can I customize the modal or embed the attached script in the menu
