icons in context menu after upgrade.

Hello,
In the process of upgrading an application from v5 to v7 of webix, I can’t seem to get icons to display correctly despite following the online documentation. I’m using font awesome icons as the embedded to not cover my needs. However, no matter what i try i cannot get nested subitems to present the configured icon. I have modified an online sample to highlight the issue.

The full font spec is provided as infas fa-cog for example, but it’s not rendering on anything after v5. Could someone possibly point out what I’m doing wrong? Thanks for any pointers

…seems I was missing a submenuConfig:

Hello @SrvrSide ,
Please take a look at the snippet: https://snippet.webix.com/a3wy47lu
To use the Font Awesome 4 icons, add the following line inside the section of your HTML page:

<head>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
</head>

Please read the migration guide to Webix 6.0.
