Is there a way to hide the custom dropdown menu whenever I click outside of it?
After trying the code below, I noticed that it hides even if I click on an element inside the dropdown menu:
<button class="btn btn-primary btn-sm mt-1" type="button" id="dropdownMenuButton" data-toggle="dropdown" (click)="toggle()" (blur)="toggle()" aria-haspopup="true"
aria-expanded="false">
Tools
</button>
To achieve this functionality, you can set up an event listener on the window that changes the state of a boolean variable associated with the dropdown menu when the user clicks outside of the dropdown or its toggle button. Here's an example code snippet:
@ViewChild('dropdown', {static: false}) protected dropdown: ElementRef;
@ViewChild('toggledropdown', {static: false}) protected toggleDropdown: ElementRef;
...
constructor(private renderer: Renderer2, protected router: Router) {
this.renderer.listen('window', 'click', (e: Event) => {
if (e.target !== this.dropdown.nativeElement && !this.toggleDropdown.nativeElement.contains(e.target)) {
this.dropdownOpened = false;
}
});
}
The condition in the if statement ensures that the dropdown menu remains open when either the dropdown itself or its toggle button is clicked.
Clicking the menu will trigger the (click)="toggle()" event.
If you click outside of the menu, the (blur)="toggle()" event will hide it. The choice is yours on what action to bind to.
