Create the stack structure

Stacks are added to an extension’s structure in a /stack directory that is at the same level as the extension’s ext.json file.

Each stack should have its own child directory in the /stack directory. The following example shows the directories and files that can be included for a stack:

<extension-name> : the root folder of your extension
     ext.json
     stack/
         <stack-type>/
             stack.json
             templates/
                stack.template
             less/
                stack.less
                stack-variables.less
             locales/
                <locale code>.json
                <another locale code>.json
