Can I use css and *ngIF conditions?-CodePudding

i want to use this

but the reality

As for the css, do I use visibilityor is there something else that works?

mycode Html

 <div  *ngIf="PrhdService.prCheck01"> //<--- this
          <mat-form-field  appearance="outline">
               <mat-label>date dd/MM/yyyy</mat-label>
               <input matInput name="date" formControlName="date" type="text" required readonly>
               
          </mat-form-field>
     </div>

mycode typescript Should I add something to the function? how?

    prCheck01: boolean = false
    prCheck02: boolean = false
    prCheck03: boolean = false
    type!: string

    feedDdataEdit(prno: string) {
      this.PrhdnetworkService.getPr_prhd(prno).subscribe({
      next: data => {
    
      var {  type } = { ...data }
      this.form.setValue({ type})

      this.type=type 

      if (type == '01') {
        this.typeRespones = '01'
        this.prCheck01 = true
        this.prCheck02 = false
        this.prCheck03 = false


      } else if (type == '02') {

        this.typeRespones = '02'
        console.log(this.typeRespones)
        this.prCheck01 = false
        this.prCheck02 = true
        this.prCheck03 = false
    
    } else if (type == '03') {
      this.typeRespones = '03'
      this.prCheck01 = false
      this.prCheck02 = false
      this.prCheck03 = true
    }

How can I use them together?

Thanks a lot.

You can use <ng-template> as place holder and render it only when your *ngIf is falsy.

<ng-template #placeHolder>
    <div ></div> 
</ng-template>

Now add it after the *ngIf as your "else" statment:

<div  *ngIf="PrhdService.prCheck01"; else placeHolder>

I'm not sure if I understand correctly (please correct me), but you can use NgClass to apply css classes conditionally.
