Im stuck guys in this code, please help me, i want to make tag li at the right side

Please post a link to your codepen.

Refer to the bootstrap docs.
https://getbootstrap.com/components/#navbar

Make sure you’re using the right version of bootstrap. The quick-add in codepen uses version 4 (not a problem if that’s your intention). Otherwise, use this URL for version 3:
https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css

thank you so much really help me

Try using style=“float:right;” inside the li tags.
