That's an interesting problem! While that CSS helped in this case, I don't think that it would help universally? On different pages, it might make the body look weird. For different Koha instances or on different devices, it might be too much or not enough? An alternative could be to add the following to the dropdown in question: max-height: 33vh; overflow-y: auto; That should work pretty well across different devices and different Koha instances. I suppose that brings us back to the same question of where to implement the CSS though. It would be needed for any Bootstrap dropdown menu that had many options, no?

Hi, We face a very strange bug : When there are a lot of libraries (66), when we go to Administration › Library groups Clicking on "Add library" will display a very long combo-box. We can not click on the last ones. Even when scrolling the page stops before the combo-box end. We solved by adding CSS : body#admin_library_groups { min-height: 300vh; } My question is should we had this to all pages ?
