How to get list of all tags ?

[Dru Vagale]

under this defined tags section I have quite a number of tags which is present. See the below image

I want to get this all the tags in a speicific part of the template, i am using this code. 
 

<ips:template parameters="$baseUrl, $count, $id, $action, $elements, $hiddenValues, $actionButtons, $uploadField, $class='', $attributes=array(), $sidebar=NULL, $form=NULL, $errorTabs=NULL, $tags=array()"/>

                <h1>Suggested Tags</h1>
                {{if \count( $tags )}}
                    {{foreach $tags as $tag}}
                        {$tag}
                    {{endforeach}}
                {{else}}
                    No tags found.
                {{endif}}

But therefore it's not returning any tags.
