The issue with Angular2 Material select dropdown is that it remains open even after being toggled

Exploring the world of Node.js, I am delving into utilizing the dropdown feature from Angular Material. However, an issue arises once the dropdown is opened - it cannot be closed by simply clicking another region of the page. Additionally, the dropdown list is not fitting properly within the bootstrap grid where it's placed. Here's a visual representation of the opened dropdown:

In my package.json file, these are the key Material dependencies (among others):

"@angular/material": "^5.2.5",
"@angular/animations": "^5.2.10",
"@angular/cdk": "^5.2.5",
"hammerjs": "^2.0.8",

I've structured my project with submodules, including relevant imports in both parent and child modules. The necessary imports look like this in the parent module:

imports: [
    MatSelectModule,
    ReactiveFormsModule
]

And the same imports are included in the child module as well.

Within the actual component that employs the dropdown, here is the html snippet:

<div class="row col-sm-5">
         <mat-form-field>
                <mat-select placeholder="Toppings" [formControl]="toppings" multiple>
                        <mat-option *ngFor="let topping of toppingList" [value]="topping">{{topping}}</mat-option>
                 </mat-select>
          </mat-form-field>
  </div>

The corresponding TypeScript code includes:

toppings = new FormControl();

toppingList = ['Extra cheese', 'Mushroom', 'Onion', 'Pepperoni', 'Sausage', 'Tomato'];

If there are any insights on what could be going wrong in my setup, I'd greatly appreciate the guidance!

Integrate a material theme into your primary CSS/SASS file:

@import "~@angular/material/prebuilt-themes/indigo-pink.css";

Alternatively, you can include it in the head section of your index.html file.
