Separator line in the MathJax menu

[albert....@gmail.com]

Dear All,

In the MathJax context menu there are a number of items like "Show Math As", "Math Settings" etc. The "Math Settings has a number of items like "Zoom Trigger" and "Zoom Factor" and below the "Zoom Factor" there is a separator line. In version 2.2 I was able to remove / hide this line by:
  MathJax.Menu.menu.items[2].menu.items[2].hidden = true;
in the function:
  MathJax.Hub.Register.StartupHook("MathMenu Ready",function ()

In version 2.7.1 (I didn't try intermediate version) this does not work anymore, I get the error message:
  TypeError: MathJax.Menu.menu.items[2].menu is null

How can I remove / hide the line?

Thanks in advance.

Best Regards,

Albert

Hi,

I would not hack this by JavaScript but simply add 

   .MathJax_MenuRule { 

        display: none

    }

to your CSS (or, if you prefer, to your MathJax configuration, cf. http://docs.mathjax.org/en/latest/reference/CSS-styles.html)

Regards,

Peter.

Dear Peter,

Thanks for this quick answer.
This solution does work, but has as disadvantage that all separator lines in the menu disappear and I have to add an extra file to my project. I already have the described startuphook and inhere I already remove some of the other items (to minimize the total distribution size, I cannot use a CDN as some users don't have internet access / very strict firewall rules on the computers where the documentation is show as part of the program).
In the startuphook I have e.g. already:
           var a=MathJax.Menu;
           a.menu.Find("Language").hidden = true;
and
          a.menu.Find("Math Settings","Scale All Math ...").hidden = true;
so some hacking is already done.

Best Regards,

Albert

Dear Peter,

As I have already a section:
  <script type="text/x-mathjax-config">
I added here:
MathJax.Hub.CombineConfig("MathMenu",{
styles: {
   ".MathJax_MenuRule": {
        display: "none",
    }
}});

So the extra file is gone. All separator lines are gone as well but this is not a big issue for me.

Best Regards,

Albert

In a recent version of MathJax (2.5?) the .menu property was changed to .submenu, so I think what you want is

MathJax.Menu.menu.items[2].submenu.items[2].hidden = true;

(the top-level menu is still menu, if I recall correctly).

Dear Davide,

Thanks for the answer.
This is indeed the case, when using submenu the mentioned division line disappears.

Best Regards,

Albert
