Themes

Hi
I am going to see if I can find where the problem is in the Fordson theme. However I do not have Moodle 3.7 only Moodle 3.6 but it should be the same as 3.7.
I will let you know how I get on and hopefully find a solution.
It is probably something simple within the coding of that menu as not many know how RTL is supposed to work. It may just be a simple thing that needs to be added in the code of a renderer file in Fordson.

If you want to apply your css rules only in rtl mode, every css rule you add should be prefixed with body.dir-rtl, for example

Do not write
h1  {
    font-weight: bold;
}

but 

body.dir-rtl h1 {
    font-weight: bold;
}
