Using Liferay Util HTML Bottom

The HTML bottom tag is not a self-closing tag. Content placed between the opening and closing of this tag is moved to the bottom of the <html> tag. When something is passed using this taglib, the bottom.jsp is passed markup and outputs in this JSP.

This tag also has an optional outputKey attribute. If several portlets on the page include the same resource with this tag, you can specify the same outputKey value for each tag so the resource is only loaded once.

The example configuration below uses the <liferay-util:html-bottom> tag to include JavaScript (a common use case) provided by the portlet’s bundle:

<liferay-util:html-bottom outputKey="htmlbottom">

    <script src="/o/my-liferay-util-portlet/js/my_custom_javascript.js" 
    type="text/javascript"></script>

</liferay-util:html-bottom>

Now you know how to use the <liferay-util:html-bottom> tag to include additional resources in the bottom of the page’s HTML tag.
