I want to display a select form with the posibility to select multiple categorys.
With wp_dropdown_categories you can only select one.
Is there any WP function, to do this, or have I to do it per querry to the table wp_terms. If this is so, how can I tell there categories from tags.
PS. I hope, it's possible, to understand my question, but I'm not acustomed to write in english.
