If you want to adapt the user interface or if you want to modify the visible menus, you have the possibility to create templates, for that, go to the Teplates menu of the plugin.
You can add as many blocks as you want which will contain the different menus or panels that you choose.
Each block must have a unique id, a category (menu or panel), if it is collapsed or expanded, the target location, and the items that compose it. In case you choose a panel category, it is preferable to put only one item there, or you will need to adapt the CSS according to the items that you will place there.
Once you have finished creating your templates, you can select them on the configuration page for a custom product.
You can check that your template is working properly by going to a product page.
