Customizing with Angular Material

Example of how you can completely customize the query component with another library like Angular Material. For the full example, please look at the source code provided in the demo.

app.component.html

<mat-option [(ngModel)]='query' [config]='config'>
  <ng-container *queryButtonGroup="let ruleset; let addRule=addRule; let addRuleSet=addRuleSet; let removeRuleSet=removeRuleSet">
    <button type="button" mat-button (click)="addRule()">+ Rule</button>
    <button type="button" mat-button (click)="addRuleSet()">+ Ruleset</button>
    <button type="button" mat-button (click)="removeRuleSet()">- Ruleset</button>
  </ng-container>
  <ng-container *queryRemoveButton="let rule; let removeRule=removeRule">
    <button type="button" mat-icon-button color="accent" (click)="removeRule(rule)">
      <mat-icon>remove</mat-icon>
    </button>
  </ng-container>
  <ng-container *querySwitchGroup="let ruleset">
    <mat-radio-group *ngIf="ruleset" [(ngModel)]="ruleset.condition">
      <mat-radio-button value="and">And</mat-radio-button>
      <mat-radio-button value="or">Or</mat-radio-button>
    </mat-radio-group>
  </ng-container>
  <ng-container *queryField="let rule; let fields=fields; let changeField=changeField">
    <mat-form-field>
      <mat-select [(ngModel)]="rule.field" (ngModelChange)="changeField($event, rule)">
        <mat-option *ngFor="let field of fields" [value]="field.value">{{field.name}}</mat-option>
      </mat-select>
    </mat-form-field>
  </ng-container>
  <ng-container *queryOperator="let rule; let operators=operators">
    <mat-form-field>
      <mat-select [(ngModel)]="rule.operator">
        <mat-option *ngFor="let value of operators" [value]="value">{{value}}</mat-option>
      </mat-select>
    </mat-form-field>
  </ng-container>
  <!-- Override input component for 'boolean' type -->
  <ng-container *queryInput="let rule; type: 'boolean'">
    <mat-checkbox [(ngModel)]="rule.value"></mat-checkbox>
  </ng-container>
  <!-- Override input component for 'category' type -->
  <ng-container *queryInput="let rule; let field=field; let options=options; type: 'category'">
    <mat-form-field>
      <mat-select [(ngModel)]="rule.value" [placeholder]="field.name">
        <mat-option *ngFor="let opt of options" [value]="opt.value">
          {{ opt.name }}
        </mat-option>
      </mat-select>
    </mat-form-field>
  </ng-container>
  ...
</mat-option>
