template tag called in if statement

I am wondering if there is any way that I can call a template tag from within an if statement.

I am trying to do the following.

{% for k,v in form.amenities.field.choices %}
    {% if {% check_hidden k %} %}
        {{ v }}
    {% endif %}
{% endfor %}

The {% check_hidden k %} tag returns True or False from the table for the item being looked up. I can confirm that {% check_hidden k %} returns either True or False on it's own, but I am wondering if I can wrap an if statement around it?

The app that I am working with is inherited, so I am trying to minimize the amount of changes needing to be done for now. Currently it is just being rendered as {{form.amenities}}, but I have added an additional field to the model that I now need to check before displaying the field in the template.

If there is another way that this could be done, I am open to suggestions.

Thanks in advance.

Whatever it is that check_hidden does for a choice value needs to be fixed in a fundamental way.

If the field choices are dynamic, the correct set of choices needs to be established in the view function, removing the need to do check_hidden in the template at all.

Will give you lots of ways to have dynamic choices. Many of these are done in the view function, removing the need for this kind of if-statement in the template.

It sounds like check_hidden was written as a template tag when what is needed is a filter.

{% if k|check_hidden_filter %}
