I have just set up wpsolar to index a list of articles I have on my site. A key part of this is being able to filter based on the hierarchy of categories the article belongs to.
If I turn off the “Show the hierarchy” option in configuration section 2.4 Filter, the hierarchical categories become serialized into a list and all get displayed.
However, if I turn on “Show the hierarchy,” only the top-level categories are displayed, and I have no mechanism for displaying the sub-categories. Looking at the html, I do see that they are there as li elements, but the property wpsolr_hide sets them to display: none.
I am using a custom theme that’s not the Directory+ theme (that’s not going to work for my purposes). Is this the reason that a UI widget to expand the hierarchy is not present?
I don’t actually want the hierarchy to require expansion, I would rather it always be expanded. It’s possible I can achieve this by overriding the wpsolr_hide rule, but this seems weird.
I may end up breaking up my categories into separate facets, in which case this could become a moot issue for me. However, I’m still confused as to why I’m not able to disclose the child nodes in the filter hierarchy. Thanks for your help!
