Hi I seem to have it working with the following code:
<form method="GET" action="https://localhost/kenny_whelan/jobs/">
<p class="keywords col-lg-4">
<?php wp_dropdown_categories( array( 'taxonomy' => 'job_listing_category', 'hierarchical' => 1, 'show_option_all' => __( 'Any Category', 'wp-job-manager' ), 'name' => 'search_categories', 'orderby' => 'name', 'selected' => $selected_category ) ); ?>
</p>
<p class="location col-lg-4">
<?php wp_dropdown_categories( array( 'taxonomy' => 'job_listing_region', 'hierarchical' => 1, 'show_option_all' => __( 'Any Region', 'wp-job-manager' ), 'name' => 'search_categories','show_count' => 2, 'orderby' => 'name', 'selected' => $selected_category ) ); ?>
</p>
<p class="buttons col-lg-4">
<input class="advanced" type="button" value="Advanced Search" ONCLICK="window.location.href='index.php?page_id=13'" />
<input class="search" type="submit" value="Find a job" />
</p>
</form>
However why I click the submit button the results are not reflect in the job results which is odd as this was functioning correctly when I was using input fields and not drop downs.
Also in order to customise the layout of the job results section which template file would I edit.
Thanks Mike
