bootstrap multiselect dropdown width 100%

I have been using bootstrap multiselect in my web app for about 9 months now. I've been styling the width of the dropdown to be 100% like this:

    ul.multiselect-container {
      width: 100% !important;
    }

.dropdown-menu {width:100% !important;}

I just got the new version because it had an extra configuration option (onDeselectAll). Now the dropdown width is not 100%. Looking at the styling in the elements console it looks like my css should still work:

We can see in the photo of the css that .dropdown-menu {width:100% !important} is being overridden but I'm not sure what by.

Any ideas?

The below minimal example is working fine, so Bootstrap Multiselect is not override the styling. But note that in your case .dropdown-menu and .multiselect-container refer to the very same elements (the ul, like in the example below. So applying the styling to both classes, like you did is not necessary and may cause what you see in the inspector.
