Versions This change has been applied to master, 29 and 28 so please test that it works on each version. Themes Please follow the testing instructions below on both the "clean" theme (or bootstrapbase) and the "base" theme. The changes to the file picker should work on both. Browsers Please follow the test on each of the themes on each of the major browsers to ensure compatibility. E.g. Chrome, Firefox, Safari etc. Testing Instructions Standard Screen Log in with a site admin that can create courses Create a new course Administration block > site administration > manage courses and categories > Create new course Scroll to the "Description" section In the "course summary" click on the far right icon (paper with paperclip) "Manage files". This should pop up the manage files dialogue Click on the left icon (paper with a "+" sign) "Add...". This should pop up the filepicker dialogue. CHECK: The filepicker dialogue should fit within the manage files window CHECK: The filepicker dialogue should not be draggable CHECK: The filepicker should be standard styling (the nav list on the left and item block next to it on the right) not responsive (nav list on top with item block below it) Close those dialogue screens and return to the create course page In the "course summary files" part of the Description section, click on the left icon (paper with a "+"). This should open the filepicker dialogue on it's own, not within the manage files dialogue. CHECK: The dialogue should be 873px wide (as it was before these changes) which is slightly wider than the manage files dialogue. CHECK: The filepicker dialogue should be draggable CHECK: The filepicker dialogue should be in standard styling, not responsive. Responsive Screen (< 768px wide) CHECK: Repeat steps above to open the filepicker dialogue within the manage files window. This time the manage files dialogue should be full screen however the filepicker wont be. It makes it difficult to use (this is the issue I mentioned in my comment). CHECK: Open the filepicker dialogue directly (see above) and this should be fullscreen (as it was before my changes).
