Hi there,
How do you expect it to work with Dokan? The plugin is called Conditional Logic for Woo Product Add-ons and it’s designed to add conditional logic (hide\show addons fields based on certain conditions) to WooCommerce Product Add-ons plugin.
If you use WooCommerce Product Add-ons plugin with Dokan in your project, then you can set conditional logic for Add-on fields using the instructions here. If you expect Conditional Logic for Woo Product Add-ons to add conditional logic feature to some Dokan instances – then no, plugin is designed for Woo Product Add-ons specifically.
