Autocomplete results showing behind the form How can I make the autocomplete search results appear above all elements on the page? 

I have 2 forms on one page, the top form has the autocomplete text field. Immediately below that is another form. When the autocomplete results show, they are behind the second form.
I can only speculate as to how you've styled up the second form, but it might be its z-index is higher than that of the autocomplete dropdown.

Trying setting a higher z-index for the autocomplete div in your stylesheet:

#autocomplete {
  z-index: 1000;
}
