The buttons don't want be where i want

Some buttons wont be where i want.

Wen i go to other page, and i come back, the go where they was before.

Not all, but some... It's because i want reorder per seller, then i see when i have a problem.

But twitter & Facebook won't go to ther and Fundraiser also not.

Top menu items cannot be moved into a submenu.

This was a button that i make myself...

So it's not a top menu.

Well then one of us is lost.

Your screen shot clearly shows your in the MENU BUILDER.

All of the blue items across the top are top level menu items.

The screen shot clearly shows you have a top level menu item circled with a arrow pointing to a spot below a green item which are sub menu items.

So your term button is confusing. Perhaps you need to show a screen shot of your site showing exactly where this button appears.

what you want takes programming.

Or you created a wrong type of button that you can't use in that manner...

Please try to explain it more clearly

Yes, if you created a new "top menu" item and want it to now be "sub menu" item, you have to remove the "top menu" item you created and then create a new "sub menu" item in its place.  As Dean said, you can not move a "top menu" item to a "sub menu".
