Warning: Adult Website / Not Safe For Work I just came across a very interesting XF-website which has some nice features build into the "Resource Manager": <removed> 1) the most interesting feature is that you can filter the "Resource Manager"-Categories by more than just 1 Category. Clicking onto several items at the left-sidebar lets you filter by multiple Categories. Not sure how this has been implemented, but it is not showing a "Prefix" by which you can filter, but you can select various "Categories" or certain items at the left-sidebar and it filters the RM-items. 2) I do like to Category-Dropdown at the left sidebar (it expands the Category-List when you click the toggle / small arrow-icon). 3) the Masonry-Layout (grid layout) is also great by utilizing the Desandro-Masonry-script. I am wondering if this has been coded based on the standard "XF Resource Manager" (by using an Add-on) or if this has been coded from scratch ? Is this an Addon somebody has come across ?
