Please refer the image when select the child category it shows "searchfilter?field_category_tid=5" but when I select the parent it shows nothing "searchfilter?field_category_tid=4" I know this can be solved by creating contextual filters or some sort of relationship setting. But I have no idea how to do it.

Using the following guideline I managed to add my custom classes to selector. https://codex.wordpress.org/TinyMCE_Custom_Styles But Now I want to add a clear button to remove the classes How can I implement this?
