In MVC 6, how to code checkbox list in view and pass the checked values to the controller?

Sorry but most of my searches take me to old MVC codes. Any help will be appreciated.

In MVC 6 with tag helpers, how do you code a set of checkboxes:

• Use tag helper for label so clicking it will toggle the checked value
• Save (Bind?) the checked value to the IsOptionSelected property
• Pass these checked values back to Controller after clicking Submit

?

I was able to display the checkboxes with labels correctly, but I do not know how to pass the checked values back to the controller via the model. Right now, IsOptionSelected values are coming back as false.

I was also able to make the html helper for the label work but not for the tag helper. I may be also coding these all wrong so any tips will help!

Here's what I have so far:

Display:

Entity:

public class PhoneOption
{
    public bool IsOptionSelected { get; set; } = false;
    public int OptionId { get; set; }
    public string OptionName { get; set; }
}

Model:

[Display(Name = "Phone Options")]
public IEnumerable<PhoneOption> PhoneOptions { get; set; }

. . . .
PhoneOptions = repository.GetPhoneOptions();

Repository:

public IEnumerable<PhoneOption> GetPhoneOptions()
{
    IEnumerable<PhoneOption> options = new[]
    {
        new PhoneOption { OptionId = 1, OptionName = "Phone Case",       IsOptionSelected = false },  
        new PhoneOption { OptionId = 2, OptionName = "Screen Protector", IsOptionSelected = false },
        new PhoneOption { OptionId = 3, OptionName = "Car Charger",      IsOptionSelected = false },
        new PhoneOption { OptionId = 4, OptionName = "Extra Cable",      IsOptionSelected = false }
    };
    return options;
 }

View:

<div class="form-group">
    <label class="control-label">Phone Options</label>
    <div>
        @foreach (var option in Model.PhoneOptions)
        {
            <div>
                @{ string cbId = "PhoneOption_" + @option.OptionId; }
                <input asp-for=@option.IsOptionSelected type="checkbox" value=@option.IsOptionSelected id=@cbId name=@cbId />
                @Html.Label(@cbId.ToString(), @option.OptionName)
                @*This is causing invalid operation exception*@
                @*<label asp-for=@cbId.ToString()>@option.OptionName</label>*@ 
                <span asp-validation-for=@cbId class="text-danger" role="alert"></span>
            </div>
        }
    </div>    
</div>

Thanks in advance!
