How Do I Render Radio Buttons Individually With WTForms?

Solution

{% for subfield in form.sellers_filter %}
  {% if subfield.id.endswith('0') %}
    
      {{ subfield.label }} {{ subfield }}
    
  {% endif %}
  {% if subfield.id.endswith('1') %}
    
      {{ subfield.label }} {{ subfield }}
      {{ form.seller }}
    
  {% endif %}
  {% if subfield.id.endswith('2') %}
    
      {{ subfield.label }} {{ subfield }}
    
  {% endif %}
{% endfor %}
