docs: Renders a form field using bootstrap's prepended or appended text::
  
          {% crispy_addon form.my_field prepend="$" append=".00" %}
  
      You can also just prepend or append like so
  
          {% crispy_addon form.my_field prepend="$" %}
          {% crispy_addon form.my_field append=".00" %}
