Hi.

I have a php function fire via ajax call when dropdown1 has on change event.
I get in an alert message the response shown from the php query result set
however I cannot put that result into my dropdown2 control. Any suggestions please? I have this all working in a .tpl file.

Thanks so much!!

This is "chained selects" and is javascript powered. This all happens in the user's browser, and is past the point of Smarty compiling the template.

See: https://appelsiini.net/projects/chained/

The only aspect of this that Smarty would get involved is if you had several templates to choose from, and had Smarty compile the chosen template to HTML, to have that HTML as the return to the AJAX call. The choice of template could be a series of <option> tags, a series of radio buttons, a series of checkboxes, etc.
