can I use variables in another file that I'm including?
in my HTL (file1.html) I have:
<sly data-sly-test.myVar="${properties.myVarFromDialog}"></sly>
<sly data-sly-include="/file2.html"></sly>
Can I use myVar in file2.html ? I'm not getting any value. Is there a way of getting that value from file1.html to use in file2.html
You should use data-sly-template for this. You can define templates in a separate file and can pass in parameters. For an explanation on templates check the following documentation link http://docs.adobe.com/docs/en/aem/6-0/develop/sightly.html#template
