    [CLOSED] Fonts Awesome in Gray Theme

    I am trying to get the fonts awesome working with Gray theme. It works great on Triton and Graphite. Gray and Neptune dont work and all icons are missing.

    I am working with treelist example and have the code block that adds the fonts awesome based on theme. I can see that fonts awesome JS is added in fiddler BUT the icons are all missing. I also see these errors in fiddler.

    Pls assist.

    thanks

    Hello @Z!

    Understanding that the old themes were not designed to actually work with the font awesome, there may be theme-bound issues trying to reference glyphs (font icons) from them.

    Anyway, we will give it a try and let you know if there is a simple way to make them work, but it is expected the need for some considerable changes in the code, in order to map the icons to the font glyphs on these themes, like overriding theme icons with custom settings, or "faking" other themes' code in the gray one.

    We'll get back to you soon.

    Hello again, @Z!

    I've just tried your example and it, well, works fine!

    The only thing I can think of is, you've installed the wrong font version. In fact, version 5.x (current/latest) does not work with the themes, so you should get the font package from https://fontawesome.com/v4.7.0/get-started/ instead, if you want to wrap up font awesome whilst using the font in a way it would be supported by all themes.

    Hope this helps! Let us know if you still can't have it working. All I had to do was download the font, extract the package in a subfolder of the project, and point the CSS include line to that new path.
