Jinja template and if/else class replacement

I'd like to add CSS classes to a html tags based on certain "conditions".

in this case I'm using jinja macro

view plainprint?

1. {%- macro ifElseBoolTemplate(variable, trueValue="", falseValue="") -%}  
2.     {%- if variable -%}{{ trueValue }}{%- else -%}{{ falseValue }}{%- endif %}  
3. {%- endmacro %}  

{%- macro ifElseBoolTemplate(variable, trueValue="", falseValue="") -%}
    {%- if variable -%}{{ trueValue }}{%- else -%}{{ falseValue }}{%- endif %}
{%- endmacro %}

(macro saved at file : macro/formMacro.html)

view plainprint?

1. {% import 'macro/formMacro.html' as formTag with context %}  
2. ...  
3. <div class="item {{ formTag.ifElseBoolTemplate(item.isActive, "", "inactive") }}" >sample content</div>  

{% import 'macro/formMacro.html' as formTag with context %}
...
<div class="item {{ formTag.ifElseBoolTemplate(item.isActive, "", "inactive") }}" >sample content</div>

that's it
