Good article
nice tutorial. this is something i needed and it would be nice to see more texts like this. i have one question: is it possible to read the section data from the variable, but different than the section name with array format?

Yes, it's possible. Use the `datasource` section attribute:
~~~~
<opt:section name="foo" datasource="$bar">
</opt:section>
~~~~
Just remember that OPT ignores the "parent" attribute then and does not link it with the parent section, if your section is nested.
