Is it posible to use template files instead of making templates in resources-templates?
Name your template file "myTemplate.html"
Place it in "/assets/templates/myTemplate.html"
Create a template variable named "templateTV"
Make it's input type = "file"
make it's default value = "@FILE assets/templates/myTemplate.html"
Create a document template named "myTemplate"
Go back to the template variable and make it available to this template.
Then return to this template and set its contents to "[*templateTV*]"
Create a MODx document.
Set its template to "myTemplate".
Now you can edit your template file in Dreamweaver, etc. then upload it to /assets/templates/myTemplate.html, and when you refresh your MODx document you'll see your changes.
Is that what you wanted?
