We'll create fresh WordPress site with Dynacat – Dynamic Category Filter installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Dynacat – Dynamic Category. Ideal for websites that feature a huge number of categories and sub categories for posts. When your website has many categories, selecting your required category from the drop-down selector can lead to tiresome scrolling – especially when the category you want to select is near the bottom of the list.
Dynacat takes away that problem by replacing the standard drop-down list selection with a dynamic search box. To select the category for your post, simply begin to type in the search box. As you type, a list of categories appears that matches your criteria. The list changes with each letter you type, before your chosen category is easy to select.
This is designed for sites with a large selection of categories.
