The vertical menu on the XWiki Syntax guide has all of its items underlined. It should be consistent with the similar menu on the user profile. Right now there's already a CSS rule, but it's quite specific and only targets the user menu: https://github.com/xwiki/xwiki-platform/blob/c670555edf765828463accc8c69e6b0f9f1912f5/xwiki-platform-core/xwiki-platform-flamingo/xwiki-platform-flamingo-skin/xwiki-platform-flamingo-skin-resources/src/main/resources/flamingo/less/general.less#L182 It should be extended to include all of the vertical menu elements. Note that after a quick search I could not find the vertical menu component on https://www.xwiki.org/xwiki/bin/view/Documentation/DevGuide/FrontendResources/ |
