Pass 'disabled' to gform_pre_render_2 for dynamically populated dropdown

    Based on the post about populating a dropdown dynamically, I have a drop down that pulls from my CATEGORIES, from which I want the user to be able to select ONLY a category that has parent (e.g. If i have men, women and children as parent categories, and each of them contains "clothes" and "shoes" I want the user to only be able to select either Men > Clothes or Men > Shoes, but not just MEN. I'm passing the correct values to form and it's picking them up, but I can't figure out how to indicate which values (the parent categories) should be disabled/unavailable for the user to select. Thanks. /sarah

    Hi Abacus,

    You could check if the current category in the loop as any children and if so, skip it and move on the next category.

    [php]
$children = get_categories(array('child_of' => $category->term_id));
if(!empty(children))
    continue;

    Hi.. I want to SHOW the parent category, just not allow it to be selected. This would just not show the parent category at all, right?

    Hi Abacus,

    Ah, I see. That makes this a little trickier. What you could do is the same check, but instead of skipping the parent category, you would set the value to a special key, like "CAT_PARENT". Then you could use a little jQuery like this to disable those elements:

    [js]
<script type="text/javascript">
    jQuery(document).ready(function($){

        $('.populate-cats option[value="CAT_PARENT"]').attr('disabled', true);

    });
    </script>
