I am using the jQuery autoplete widget in my project. It is working fine expected that the dropdown menu appends to the body instead of the input. My Codes are as follows:

html

    <div class="flddiv fw"  id="mealmentsdiv">

    <input id="foodautotest"  type="text" placeholder="autoplete">

</div>

Javascript

function getVectors(VectorTypeID) {

Vectortype[VectorTypeID]={}

return $.ajax

({

    url: "functions.php",

    data: {
        method: "getvectors",
        VectorTypeID:VectorTypeID
    },

    method: "post",

    dataType: 'json',

    success: function(result)

    {
        Vectortype[VectorTypeID]=result



        switch(VectorTypeID){

            case 1:

                $.each(result,function(key,value){

                    strfoods.push(value)

                })

                $( "#foodautotest" ).autoplete({
                    source: strfoods,
                    appendTo: "#foodautotest",

                }

                })
                break
        }

    }

});

}

As you mentioned, the autoplete dropdown menu appends to the body. Because of the absence of appendTo option

Regardless of the value, if no element is found, the menu will be appended to the body.

By providing the option to the div with an absolute position solves the issue.

HTML

<input id="foodautotest" type="text" placeholder="autoplete">
<div id="autoplete-cont"></div>

JS

appendTo: '#autoplete-cont',

CSS

#autoplete-cont {
  position: absolute;
}

DEMO

var strfoods = ["Bread", "Beef", "Mango", "Salad", "Eggs", "Chicken", "Pork", "Cabagge", "Ice Cream", "Banana", "Rice", "Xmas Cake", "Cassava", "Potatochip", "Chickhen Curry", "Steak Sandwich", "Bbq Pork", "Pavalova", "Calamari", "Sushi", "Roast Beef", "Duck", "Asparagus"]

function getVectors(VectorTypeID) {
  console.log("Got Vectors:", strfoods);
  $("#foodautotest").autoplete({
    appendTo: '#autoplete-cont',
    source: strfoods
  });
}

getVectors();

I was unable to replicate the issue as you posted it. I tested the following code:

$(function() {
  var strfoods = [
    "ActionScript",
    "AppleScript",
    "Asp",
    "BASIC",
    "C",
    "C++",
    "Clojure",
    "COBOL",
    "ColdFusion",
    "Erlang",
    "Fortran",
    "Groovy",
    "Haskell",
    "Java",
    "JavaScript",
    "Lisp",
    "Perl",
    "PHP",
    "Python",
    "Ruby",
    "Scala",
    "Scheme"
  ];

  function getVectors(VectorTypeID) {
    console.log("Got Vectors:", strfoods);
    $("#foodautotest").autoplete({
      source: strfoods
    });
  }
  
  getVectors();
});

<link rel="stylesheet" href="//code.jquery./ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery./jquery-1.12.4.js"></script>
<script src="https://code.jquery./ui/1.12.1/jquery-ui.js"></script>
<div class="flddiv fw" id="mealmentsdiv">
  <input id="foodautotest" type="text" placeholder="autoplete">
</div>

This is working as expected.

You mentioned your page is using a CSS Grid, yet you did not include any CSS in your example. In regards to the appendTo option, pleas see:

Which element the menu should be appended to. When the value is null, the parents of the input field will be checked for a class of ui-front. If an element with the ui-front class is found, the menu will be appended to that element. Regardless of the value, if no element is found, the menu will be appended to the body.

Note: The appendTo option should not be changed while the suggestions menu is open.

So by default, it is being appended to the body with position so it appears "under" the input field. I think you want to append to the parent, #mealmentsdiv and not the <input> element itself. There is no way to test this with your given example as it does not contain all the proper elements or styles.

As the widget creates elements, to display the menu, this cannot be appended to an Input field. It can be appended to the parent and is then positioned to appear under the field.

I dont think it's even possible to render elements inside an input element. How about to render the dropdown next to the input as a sibling.

html

<div>
    <div class="flddiv fw" id="mealmentsdiv">
    <input id="foodautotest" type="text" placeholder="autoplete">

    <!-- let's take this one as parent-->
    <div id="autoplete-wrapper"></div>
</div>

js

$( "#foodautotest" ).autoplete({
    source: strfoods,
    appendTo: "#autoplete-wrapper",
});

If this does not fit your needs please add more informations to the question why you need to append the dropdown to the input element.

EDIT: Please make sure that your JQuery and JQueryUI is up to date, because there are some inpatibilities that caused errors in JQuerys offset function.
