I am working on a wordpress website and i am little stuck into one situation, what i want is that to add multiple and dynamic slug values from job listing taxonomy, right now i have to manually insert the slug name into 'option_none_value' => '', if no category is selected. I searched a lot on google but didn't find any relevant solution.
wp_dropdown_categories(
array(
'show_option_none' => 'All Job-types',
'option_none_value' => '',
'value_field' => 'slug',
'taxonomy' => 'job_listing_type',
'name' => 'search_type',
'orderby' => 'name',
'class' => 'select-on-home',
'hierarchical' => true,
'hide_empty' => true ,
'show_option_all' => esc_html__('','workscout'),
'echo' => 0
)
);
