i'm trying to use the Mikio theme with an indexmenu (from the plugin with the same name) in the sidebar. The indexmenus work fine, when they are on the page itself. However, when they are in the sidebar, they are completely broken (see screenshots).
I didn't have this problem with the bootstrap3 theme or the default dokuwiki theme. Does anyone know what might be causing this? I tried this with a fresh installation of dokuwiki (only Mikio and Indexmenu plugin installed).
Thank you for your help!
