Hello, I am trying to create a multiselect attribute with many options for use in layered navigation. The problem I am encountering is the option for filterable results in the layered navigation will be automatically disabled when the attribute has more than 15 selectable options. There is no warning presented on the page, nothing is logged to the exception log, and nothing is logged in the system/debug logs that would indicate this is a problem. I'm assuming this is intended behavior for performance purposes but I was wondering how I might bypass this or if there is a better way to accomplish what I am trying to do.
For reference, my specific use case is for matching watch straps to watches, enabling customers to ensure they are buying a watch strap with the proper size for their watch using the layered navigation.
