I am using Sharetribe opensource. When a user creates a listing, by default Sharetribe provides the option to choose a category and a sub-category. I want the user to be able to choose multiple sub-categories under a category when they create a listing. I understand this is not standard and requires customisation.
Wondering if anyone here has done this before? If so, technically how did you achieve this and what issues did you face?
Currently, we have done this and are having difficulties with making the search results to display listings correctly i.e., to show the same listing when the user searches under different sub-categories. For example, show the same class listing when a user searches for English or Math or Science sub-categories.
