问题 I recently asked this question and it was well answered. But I have another question: How to detect toggle status in ng-bootstrap dropdown where there are several dropdowns?

问题 When I heard bootstrap 4 was going to employ flexbox for a grid system I was really excited. I thought that this would deploy the fast and useful element sizing that flexbox is known for. However it seems that it just adds some (major) functionality to the current 12 col grid system. Does Bootstrap 4 make it any easier to relate column widths in a non 12 col layout? Like how flex boxes can be related to each other simply by specifying the horizontal space to divide using flex-item properties

问题 Why isn't my bootstrap navbar not collapsing? The toggle button shows up but when I click it, nothing happens. (Written in React so using className instead of class.) I even tried copying and pasting directly from the Bootstrap example and it still doesn't work. Am I forgetting to import something somewhere? I also tried copying and pasting from this example from this other question on stackoverflow, didn't work. <nav className="navbar navbar-default navbar-fixed-top navbar-shrink"> <div
