Hi, I've got the same problem with a dropdown menu is not hiding on Win 10 in Chrome and Edge. When I run my app in Explorer of older versions it works fine.

What is your MDB package version because we fixed this issue earlier (v4.17.) Turn off the system's animation may cause this problem.

Best, Tomek

Issue appears to still be occurring in v4.19. I ensured my system animations are turned on, however, some of my dropdown menus collapse while others don't. Even copy/pasting a working menu doesn't work for the pasted menu.

Could you specify which ones work and which don't?

Everything works for me except Material dropdown with an element from here: I found out that the href attribute must be provided. With it, everything works as expected and you can close the dropdown using an esc key.

Best regards

This problem is still there and to test, just create a Windows 10 sandbox, install chrome, then go to the MDB navbar page. Dropdowns don't close. I can tell you that it's a problem with the animations. In mdb.js if you modify dropdownEffectData and comment out the following lines, it fixes the problem. Might be a better way to disable the animations, I am not sure:

return { target: target, dropdown: dropdown, dropdownMenu: dropdownMenu //effectIn:'dropdown-in') || effectInDefault, //effectOut:'dropdown-out') || effectOutDefault };

Hi. We can't turn off the animation completely. We will try to fix it in a different way. For now, you can try to turn on box animation. This should solve the problem

Hi. You use windows and have disable window animations?

Best, Grzegorz.

Just discovered this issue myself - i did actively disable a win10 box animation controls for the simple reason i did not need that feature and did not put 2 and 2 together - I certainly confirm above that disabling the os animate feature stops "some" dropdowns from hiding - whats not confirmed is why only "some" - it kinda appears only dropdowns triggered by the "a" tag stops workings while buttons are fine - the MDB example page shows this behavior where only some dropdowns work and others don't (while the os animate feature is disabled)

Thank you for your feedback. We will investigate this problem.

Same issue here. What was the resolution? This seems to only be happening in my Virtual Machine environments that have a graphics card as a passthrough.

I'm having the same issue with Material Dropdowns (defaults are ok). Everything was working fine until some days ago, but now every time I click on a material dropdown it never disapears. This is happening with Chrome 75.0.3770.100 and also Opera 62.0.3331.43 on Windows 10.

It's not related specifically to my application, since the same happens with this site (image attached).

Something is preventing the event triggering that would remove the show class from dropdown-menu, but I can't figure out what is happening.

Hi, I think it has to be a niche problem with your environment. Maybe clear chashe/cookies ? or try on another browser because I checked this problem and everything works fine.

I have the same problem - did you have any luck with this?


MDBootstrap staff commented 5 years ago

Like I said in the post above. This has to be a niche problem with your environment. Please provide some information about your usage of this component. What Os/Browser/Device/ are you using? We couldn't recreate this behaviour in our test environment and because of that, we don't have any further answers to this topic.

MDBootstrap staff answered 5 years ago

Hey Captain!

The problem is that your snippet works fine in every single environment I can test it in. It needs to be a problem with your environment. Maybe clear chashe/cookies? I believe there is nothing I can do for you because this is a basic use of dropdown that is pretty simple and never failed before.
