I am using this multi-select dropdown (https://www.npmjs.com/package/ng-multiselect-dropdown) to achieve multi-selection in my angular project. The strange issue i am facing is that in its demo and in my stackblitz demo( https://stackblitz.com/edit/angular-5wcm6z?file=src%2Fapp%2Fapp.component.html), it closes when i click outside. (display: none) gets applied dynamically. But when i am using the same component in my actualy project, the click event outside doesn't work and i have to click on the dropdown again to close it.
This is how i am using this dropdown.
<div class="col-md-5">
<label>Select Providers</label>
<ng-multiselect-dropdown
#dropdown
[settings]="dropdownSettings"
[data]="providers"
[(ngModel)]="selectedItems"
name="onlyBillerProviders"
(onDropDownClose)="onDropdownClose(selectedItems)"
>
</ng-multiselect-dropdown>
