Custom location – change form style

Hi,

I’d like to display search form in a custom location, in a child-theme file .php.

<?php echo do_shortcode( ‘[ivory-search id=”6391″ title=”my-title”]’ ); ?>

This works fine, but how can I change form style ?
It is the default one, and I’d like to be dropdown style, or sliding style or full-width style or popup style.
These options seems to be only available if I choose “Display search form” -> Primary Menu, which is not my case.
Is there a parameter for the shortcode allowing to choose form style ?

Thanks in advance
