After activating the third layer of sub-sub-categories, as explained in [Sub-sub-categories - #7 by Michael\_Uray](https://meta.discourse.org/t/sub-sub-categories/139309/7), we are observing certain regressions of this (undocumented) feature. Looking at the visual glitch described in [Hide sub-sub-categories from /categories listing?](https://meta.discourse.org/t/hide-sub-sub-categories-from-categories-listing/180118), it seems the CSS for subcategories does not apply to sub-sub-categories equally, probably due to some kind of selector issue. ![image](https://global.discourse-cdn.com/meta/original/4X/c/f/6/cf68de1d0e77db6cf5eb954bdfec3f0b34e300a4.png) ![image](https://global.discourse-cdn.com/meta/original/4X/a/7/6/a769746be237dbd9177300bddf5defb5f28f1456.png) It would be really nice, if one could optionally hide sub-sub-categories from this view and have it use an unadapted display there. The regression in [Sub-sub-categories - #16 by frhun](https://meta.discourse.org/t/sub-sub-categories/139309/16) does not appear to be present anymore. --- _[View the full topic](https://meta.discourse.org/t/sub-sub-categories-css-regressions-and-additional-functionality-to-customise-their-behaviour/298035)._
