Template-driven forms MDB Pro component

In this section, you will find on how to use our select component in template-driven forms.

Remember to import the FormsModule into your app.module.ts file.

Preselected value

Bind in the two-way ngModel from component.html with the selectedValue in the component.ts file


        <div class="md-form">
          <mdb-select-2 [multiple]="true" placeholder="Choose your option" label="Example label" [(ngModel)]="selectedValue">
            <mdb-select-all-option>Select all</mdb-select-all-option>
            <mdb-select-option *ngFor="let option of options" [value]="option.value">{{ option.label }}</mdb-select-option>
          </mdb-select-2>
        </div>
      

        import { Component } from '@angular/core';

        @Component({
        selector: 'defaultvalue-material-select-example',
        templateUrl: 'defaultvalue-material-select.html',
        })

        export class DefaultValueMaterialSelectComponent {
          options = [
            { value: '1', label: 'Option 1' },
            { value: '2', label: 'Option 2' },
            { value: '3', label: 'Option 3' },
          ];

          selectedValue = ['1'];
      

Get selected value

Get selected value with the ngModelChange event, which fires every time you select an option.


        <div class="md-form">
          <mdb-select-2 [multiple]="true" placeholder="Choose your option" label="Example label" (ngModelChange)="getSelectedValue($event)" [ngModel]="selectedValue">
            <mdb-select-all-option>Select all</mdb-select-all-option>
            <mdb-select-option *ngFor="let option of options" [value]="option.value">{{ option.label }}</mdb-select-option>
          </mdb-select-2>
        </div>
      

        import { Component, OnInit } from '@angular/core';

        @Component({
        selector: 'getvalue-material-select-example',
        templateUrl: 'getvalue-material-select.html',
        })

        export class GetValueMaterialSelectComponent implements OnInit {

            { value: '1', label: 'Option 1' },
            { value: '2', label: 'Option 2' },
            { value: '3', label: 'Option 3' },
          ];

          selectedValue = ['1'];

          getSelectedValue(value: any) {
            console.log('Selected value:', value);
          }
        }

            { value: '2', label: 'Option 2' },
            { value: '3', label: 'Option 3' },
          ];
        }
      

Get selected value

            <mdb-select-all-option>Select all</mdb-select-all-option>
            <mdb-select-option *ngFor="let option of options" [value]="option.value">{{ option.label }}</mdb-select-option>

        templateUrl: 'getvalue-material-select.html',
        })

        export class GetValueMaterialSelectComponent implements OnInit {
          selectControl = new FormControl(['1']);

          options = [
            { value: '1', label: 'Option 1' },
            { value: '2', label: 'Option 2' },
            { value: '3', label: 'Option 3' },
          ];

          ngOnInit() {
            this.selectControl.valueChanges.subscribe((value: any) => {
              console.log('Selected value:', value);
            })
          }
        }

          </mdb-select-2>
        </div>
      

        import { Component } from '@angular/core';

          selectedValue = [{ value: '2', label: 'Option 2' }];

          compareFn(o1: any, o2: any): boolean {
