(Version prior to 8.0.0)
Users can now configure terms for variable products so that certain variations will be enabled for the selection in the frontend. This requires version 7.2.1 or higher of WPC Product Bundles plugin.
When adding variable products (with the mark “variable #…” at the end) to smart bundles, there is a little button written “Config terms” at the end. Users can click on that and the popup for choosing terms will be opened.
By default, if any attribute box is left blank, all terms will be used. You can type in and select some terms to be enabled in each box.
In the frontend, buyers can only see the selected terms in the drop-down list. You can also use the WPC Variations Radio Buttons plugin and show the selected variations in a clearer way:
(Version 8.0.0 or later)
With version 8.0.0, the Custom quantity and Config terms features have some changes in the display. Users can configure a different sets of min/max quantity limit for each subproduct. The Config terms feature is located at the end of this dropdown for variable subproduct. The rules for configuring the terms of attributes are still the same.
