One more question
If the user scrolls back up what would you like the drop-down to do
re-appear or stay hidden

A Menu doesn't have to be a menu in the traditional sense, stuck to the top or sides, true it's something to help users find what they are looking for, in this case, a container with the links inside could be placed anywhere on the page and indeed given a higher prominence than just being part of a top bar menu.

Anyway no matter I have done something as an example for you to look at again, I will let you know the link when its available (at the moment it's still; converting to MP4

Wayan, thanks a lot for the Videos.
It is just not what I had in mind - it seems to me that you followed the idea to make a second container beneath the fixed Nav bar, and the second container just can scroll away.
But I really want to have only the Nav bar and an opened drop down button. And you might close the drop down yxourself - or it will close automatocally when you start scrolling.

Now I think I will have to change my mind. I thought it is easy - It sounds so easy - just start with an opened drop down menu that you might close manually or that might close automatically when you start scrolling.
forget it.

BTW I couldn't find your email adress - your website is a bit confused - when you open the link
"prefer to email" it falls back on the same page and when you open the link"are you ready..." you get a 404 (on firefox).
Would be nice when you send me your email so we must not go on here in public.
Thanks for your efforts
Michael

the container beneath the nav bar IS THE DROPDOWN which is opened on page load, it can be closed by clicking on the menu dropdown button, the second dropdown button when clicked on will open it's own dropdown container, replacing the one that is open by default.

the opened dropdown container scrolls away if the user scrolls down, and opens again if the user clicks on the dropdown menu which is fixed to the top

the links for the emails etc are not relevant to my helping you from on the forum, so they were disabled

For me, or others, trying to help with solutions here, it would be of great interest to see your suggestions, Wayan. I don't have any log-in details for your site, so I'm not able to view your video.

I will put it up to Youtube

I must be getting old, I just can't imagine it envisage what he would want to achieve, I got a schematic image and thought I had got it but alas.

Wayan, I just reviewed the Video and I think I have not fully understood your construction. I could not see the "how to do" video. (link didn't work)
In the video at 2'50'' you clicked on the drop down button and the 3 links appeared again - but together with the 2 logos.
This is nearly what I want.
situation1 - you have scrolled down and the logos and the dd links have disappeared. Now you can click on the dropdown button and the links will open aagin.
situation2 - You have scrolled up on top again - you see the logos again and the Nav bar - but the formerly opened drop down button is closed. Now you can open the dd it manually.
Sorry for the misunderstanding

The how to videos haven't been done. I don't do those until a demo has been looked at. After all the person for whom I am helping may not want or lik the suggestions, it's no problem to just make a demo the how to take a lot more time and work.
It's no problem you never know someone. may come up with a better solution.
