link to an external URL

I need to add link to an external URL(youtube) in dropdown navigation menu.

I just simplly added youtube URL

https://snag.gy/aPD7Qq.jpg

When I have clicked menu it says page can not find in dolphin site.

Becaseu url is just like below.

http://www.sample.com/https://www.youtube.com/channel/UCvHSldFgDpOMSjrG2RmjxXX

Is there any how to simply jump to youtube URL?

Is there anyone know how to likn to an external URL, please let me know.

Thanks,

The URL  you are using is wrong. It's trying to point to two sites. Try this:

https://www.youtube.com/channel/UCvHSldFgDpOMSjrG2RmjxXX

Thank you for your reply.

Of corse, I have done same way but it is pointing to

http://www.sample.com/https://www.youtube.com/channel/UCvHSldFgDpOMSjrG2RmjxXX

 I have saved with

https://www.youtube.com/channel/UCvHSldFgDpOMSjrG2RmjxXX

So I have no idea how to solve this problem.

I understand your problem.

Do as I've suggested, but make sure you tick the box that says New in the section 

Target Window: Same New

It should work.

Hello srm!

As johnk42 told - if you set "Target window" as "New" and the link URL with "http" or "https" start then it would work.
