How to output functions from plugin inside theme

Question

Looks like function render_content_show_hide() is a method of class. If you want access this function directly – you can create new class instance.

If your plugin code looks like:

class Shortcode_Builder{
    //...methods
    public function render_content_show_hide( $attr, $content = null, $shortcode_name="" ) { 
        //...
    }

    //...other methods.


}

Create new instance

$builder = new Shortcode_Builder();

And access to your function $builder->render_content_show_hide()
