This plugin allow to apply some WordPress API's functions into your post/page content or as a widget.

Other Notes

Embedded output

Any functionsCapacitor request will insert <div class="functionsCapacitor">functions output</div>. Shortcode method allow to personalize main container like [fct container="HTML tag name" class="class(es) name(s)" style="CSS properties" function1="args" function2="args"]. set container="" to remove main container.

Some functions output were inserted with dedicated container like <ul class="function_name">function output</ul> or <div class="function_name">function output</div>. Personalize this container with Special functions parameters.
