Yes, I store the data in a table and populate the selectitem using codes below:

                              while (dr.Read())  
                             {  
                                 long parentPid = dr.GetInt64(dr.GetOrdinal("parent_organizations_pid"));  
      
                                 string text = dr.GetString(dr.GetOrdinal("organization_name"));  
      
                                 if (parentPid == 0)     // I expect to add an icon if the parentPid == 0  
                                 {  
                                     text = "data-icon:'home' " + text;  
                                 }  
      
                                 list.Add(new SelectListItem() { Value = dr.GetInt64(dr.GetOrdinal("pid")).ToString(), Text = text });  
                             }  

and in my .cshtml

               <div class="content-header-left col-4 mb-2">  
                    <label class="form-label fw-bold">Organization</label>  
                    <div class="input-group input-group-merge">  
                        @Html.DropDownListFor(x => x.organizationsPid, Model.organizations, new { @id="organizations", @class= "form-select" })  
                    </div>  
                    <span asp-validation-for="organizations" class="text-danger"></span>  
                </div>  

I expect to have an icon for parentPid == 0

Answer 2

the Html.DropDownListFor() generates a <select> with <option>'s. the <option> tag does not support icons. there is limited support for CSS, but Html.DropDownListFor() does not support the class element for options anyway.

typically javascript is used to implement a <select> with icons. select2 is commonly used library:
