jquery - Autocomplete issue into bootstrap modal

Question

I have a display problem in the jQuery autocomplete inside a modal dialog bootstrap.

When I mouse scroll, the results do not remain attached to the input.

Is there a way to solve this?

Here JsFiddle:

.ui-autocomplete-input {
  border: none; 
  font-size: 14px;
  width: 300px;
  height: 24px;
  margin-bottom: 5px;
  padding-top: 2px;
  border: 1px solid #DDD !important;
  padding-top: 0px !important;
  z-index: 1511;
  position: relative;
}

EDIT I found the problem:

.ui-autocomplete {
  position: fixed;
  .....
}

If the modal has scroll the issue remains!

Here JsFiddle/1.

Answer 1

The position is right that it is "absolute", while you need to specify this as an option to autocomplete:

$( ".addresspicker" ).autocomplete( "option", "appendTo", ".eventInsForm" );

Where it can anchor the box with the results in any element, I have to stop it from being anchored to the form's class!

Here is a working JsFiddle!.
