Default blank option on <select> for Safari

Question

I'm trying to make a <select> where the first <option> is empty, it is not visible in the dropdown and not selectable.

I've been researching for like 4 hours. I saw so many working options but the thing is that none of them (or at least what I've found) are working on Safari.

This is my code:

<select class="custom-select" formControlName="subindustryName">
   <option *ngFor="let subindustry of subIndustries" [value]="subindustry.value"> 
      {{subindustry.label}}
   </option>
</select>

I'm not using jQuery.

Answer 1

would this work for you? you can set style properties for an option and disable the field so it's not selectable anymore. this question seems to have been answered with another post. default empty option.

<select>
  <option disabled selected value style="display:none"></option>
  <option value="one">one</option>
  <option value="two">three</option>
  
</select>

Answer 2

Just add option with value undefined to force angular to select that value. like below

<select class="custom-select" formControlName="subindustryName">
    <option value="undefined"></option>
    <option *ngFor="let subindustry of subIndustries" 
    [value]="subindustry.value">{{subindustry.label}}</option>
</select>

and with if you want to it to be not selectable then add 'disabled' attribute with that.

EDIT AS PER COMMENT

so whatever you pasted in question should work. Here is my code snippet which is working..

<div class="form-group">
  <label class="col-md-3 control-label">Gender</label>
    <div class="col-md-3">
      <select id="gender" class="form-control" [(ngModel)]="userModel.gender" name="gender" required >
        <option value="male">Male</option>
        <option value="female">Female</option>
      </select>
    </div>
</div>

Just try with template driven approach for 'subindustryName' and check.
