That would be: wp_dropdown_categories( array( ‘selected’ … Read more

The reason your $item == $option condition is always failing is because of the way PHP compares floats! Try the following instead: echo “<option value=”$item”” . selected (abs ($item – $options) <= 0.01, true, false) . “>$item</option>” ; See Comparing floats for more info.
