I am using a themable menu supplied with the package
I am trying to get it to work in different screen widths.

If I go to about 32o it collapses to the icon menu.
If I go to full screen it shows full menu
If I however go to 400 width it wraps onto two lines which messes up the rest of the page.
I have had to stop using the layout panel as I have less control of the header.

I have also tried to get this working as a master page but the breakpoints dont work when I use it as an embedded page.

Example - logo and menu in header page
Header page embedded onto tall the other pages.

Breakpoints do not work and the menu scrolls onto wo lines instead of collapsing.

This is most likely an error in your breakpoints setup.
You will need to make sure that the breakpoints kicks in sooner (before the menu wraps)

If you need further assistance then please share DEMO project so I can see all your settings.

I do not need the complete project because that will only take more time to figure out what you have done.
