Filter by Region with Ajax
-
Wonder the wp_dropdown_categories for search filter by region have another filter or hook to override dropdown html output.
For example i have 800++ regions at ‘job_listing_region’ taxonomy, for minimalize server load i want to use selectize.js with ajax as type on the region field, because chosen.js doesn’t have ajax feature.
For now i just remove the dropdown args filter with echo => 0, and add my own field for ‘search_region’ field. But i think it still need to load all terms within wp_dropdown_categories.
