How to link StackPanel with my ViewModel?

Question

In my opinion, I have the following:

<TextBlock Text="{Binding Title}"/>

which is attached to the TitleModel Title property and , it simply and well works :

private string _title;
public string Title
{
    get
    {
        return _title;
    }

    set
    {
        _title = value;
        OnPropertyChanged("Title");
    }
}

However, my ViewModel also has a “FormFields” property , which is a StackPanel that contains a number of other UserControls:

private StackPanel _formFields;
public StackPanel FormFields
{
    get
    {
        return _formFields;
    }

    set
    {
        _formFields = value;
        OnPropertyChanged("FormFields");
    }
}

How to connect it with my idea?

ASP.NET had a PlaceHolder element , I'm looking for something with the same functionality, for example.

PSEUDO CODE:

<PlaceHolder Content="{Binding FormFields}"/>
