<txp:if_category /> container tag, 2 attributes

if_category

The if_category tag is a conditional tag and always used as an opening and closing pair, like this… 

<txp:if_category>
...conditional statement...
</txp:if_category>

The tag will execute the contained statements if the name attribute matches a category search value, or the list is an article list by category (?c=category)

Should be used in a page template; if checking the category in an article form, use if_article_category.
