Editable on edit product page
Sometimes you need to make this option editable on product page for managers, so use the Editable on edit product page option and set it to Yes.
Values are written in the database under a post meta key _latest_lowest_price. That key is stored in the postmeta database as usual price and sale price keys. If you want this key to be editable on the edit product screen set this option to Yes. The Latest lowest price editable input field will appear under the Advanced product tab in the edit product screen. It is available for simple and variable products.
Show on product page
This option defines how to integrate the plugin on product pages. Recently you'd just use blocks and edit a template, add a block named Latest Lowest Price to the place usually behind the price template and hit Save. This is if you use a modern block theme. If you use a bit older tech, like other page builders Elementor etc. you can also edit a page and make a template you need and add an widget, element or just a plain shortcode.
Still, sometimes you'd just install a plugin by hooking it onto an action. These options are for that. So, if you need this type of integration, switch the Show on product page option to the Use hook to insert.
Further set the appropriate hook/action, but usually the default one will work. Adjust priority to make the latest lowest price template appear earlier or later in page render. Default action is woocommerce_single_product_summary and priority 30.
Show on shop and archives
The same option as above, but controls how the plugin is integrated on store pages. So, use the default option if you use block themes, Elementor etc. and use hooks and actions if needed.
urther set the appropriate hook/action if needed, but usually the default one will work. Adjust priority to make the latest lowest price template appear earlier or later in page render. Default action is woocommerce_after_shop_loop_item_title and priority 20.
