Allow external script in multi-block html template to be headerized

[James Yong-2]

Hi all,

Currently setting multi-block=true for the html-template, allows inline script within the freemarker
to be transformed to an external script. This helps to reduce the CSP errors.

Propose to allow external scripts within the multi-block html template, to be rendered within the html head tag, when a new attribute data-import is set to “head” e.g.

<script src="/common/js/jquery/plugins/jsTree/jquery.jstree.js" type="application/javascript" data-import="head"></script>

With the new feature we can define external scripts in the multi-block html template that is using the library, instead of setting in layoutSetting.javaScripts.
This new feature helps with dependency management of Javascript and also reduce CSP errors.

Regards,
James

Hi all,

Created JIRA issue OFBIZ-11741.
Also uploaded a patch usimg jstree library as example.
The library will only be loaded when required.

James
