i have a drop down menu of categories. for each category is
sub-catergories. based on the category i want the second drop-down menu
to list the subcategories to correspond with the parent category. well i
have it working fine, except the second drop-down wont display the
corresponding data unless the page is refreshed twice. how do i get it to load the
first time?
i just have a simple onChange="this.form.submit();" in the parent drop
down
thanks!
Will this help? Watch for word-wrap.
