Search-input can be placed to the site header or into the page content text. Use shortcode [tableon_drop_down].
- create new TABLEON table on the plugin backend
- set all necessary options you want for the table
- open page where you want to place shortcode
- drop into the page content shortcode [tableon_drop_down id=7] where 7 is ID of the table
- to place shortcode, for example into the site header, open file header.php and place there code:1<?php echo do_shortcode('[tableon_drop_down id=7 placeholder="enter a post title part, for example: puma"]'); ?>
