Hello!
I'm going to create a module. I have known that there is a possibility to add the reference at some already described parameter in <config> section of manifest file for a new module. As I understood it can be done by pointing the value of addfieldpath attribute in <fieldset> tag. I didn't find the information about it in description of a syntax of a manifest file (https://docs.joomla.org/Manifest_files).
I'm going to use configuration parameter to create a dropdown filter with all existing product categories of Virtuemart 3 component. But I didn't understand what the value should I use for addfieldpath attribute for that.
Please explain me what values should be passed to the value of an addfieldpath attribute in a <fieldset> tag in <config> section of manifest file.
From VM product module:
<fields name="params" addfieldpath="/administrator/components/com_virtuemart/fields">
<fieldset name="basic">
<field
name="virtuemart_category_id"
type="vmcategories"
value_field="category_name"
label="MOD_VIRTUEMART_PRODUCT_CATEGORY_ID"
description="MOD_VIRTUEMART_PRODUCT_CATEGORY_ID_DESC"
/>
</fieldset>
</field>
