    Prevent Posting In Main Category Easy Fix (javascript)

    Hi this is the easiest way I have come up with to prevent users from selecting and posting in main categories.

    Step 1: Open includes/form/step1.php

    Step2: Locate the following code:
    Code:
     <?php
                            if (get_option('cp_price_scheme') == 'category' && get_option('cp_enable_paypal') == 'yes') {
                                cp_dropdown_categories_prices('show_option_none='.__('Select one','cp').'&class=dropdownlist&orderby=name&order=ASC&hide_empty=0&hierarchical=1&exclude_tree='.CP_BLOG_CAT_ID);
                            } else {
                               wp_dropdown_categories('show_option_none='.__('Select one','cp').'&class=dropdownlist&orderby=name&order=ASC&hide_empty=0&hierarchical=1&exclude_tree='.CP_BLOG_CAT_ID);
                            }
                            ?>
    Step 3: Paste in this tiny javascript directly underneath and outside of the php above
    Code:
    <script type="text/javascript">
    var dropdown = document.getElementById("cat");
    function removeOptions(dropdown)
    {
    var i;
    for(i=dropdown.options.length-1;i>=0;i--)
    {
    if(dropdown.options[i].className === 'level-0')
    dropdown[i].disabled="disabled";
    }
    }
    </script>
    Step 4: Save php document and you should be all set

    If you wanted to get real fancy and correct you could do a replace on the className of level-0 on the selct with an optgroup then append the close optgroup at the end of the array, but this is the quickest.

    Hope this helps someone (only tested in ie8 and ff 3 - let me know if its broken somewhere else)
