How to create a drag and drop feature for reordering the images using HTML CSS and jQueryUI ?

Given an images gallery and the task is to re-arrange the order of images in the list or grid by dragging and dropping. The jQuery UI framework provides a sortable() function which helps in re-ordering list items by using the mouse. With this functionality, the list items become interchangeable. The jQuery UI provides a sortable() function with default draggable properties. All the list elements in the HTML document are interchangeable and re-ordered for displaying. The user can drag and drop elements to a new position with the help of the mouse. Other elements adjust themselves to fit in the list.

Creating structure: In this section, we normally include the required jQueryUI link and libraries. Also, we will create a basic image gallery where we will perform the drag and drop functionality to reorder the gallery list.

Including all the required jQuery and jQuery UI libraries:

<link href = “https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css” rel = “stylesheet”>
<script src = “https://code.jquery.com/jquery-1.10.2.js”></script>
<script src = “https://code.jquery.com/ui/1.10.4/jquery-ui.js”></script>

HTML code to create structure:

<!DOCTYPE html> 
<html> 
<head> 
    <title>

        using HTML CSS and jQueryUI? 
    </title> 
</head> 
       
<body> 
    <h1 style="color:green">GeeksforGeeks</h1>  
      
    <b>Drag and drop using jQuery UI Sortable</b> 
      
    <div class="height"></div><br> 
      
    <div id = "imageListId"> 
        <div id="imageNo1" class = "listitemClass"> 
            <img src="images/geeksimage1.png" alt=""> 
        </div> 
          
        <div id="imageNo2" class = "listitemClass"> 
            <img src="images/geeksimage2.png" alt=""> 
        </div> 
          
        <div id="imageNo3" class = "listitemClass"> 
            <img src="images/geeksimage3.png" alt=""> 
        </div> 
          
        <div id="imageNo4" class = "listitemClass"> 
            <img src="images/geeksimage4.png" alt=""> 
        </div> 
          
        <div id="imageNo5" class = "listitemClass"> 
            <img src="images/geeksimage5.png" alt=""> 
        </div> 
          
        <div id="imageNo6" class = "listitemClass"> 
            <img src="images/geeksimage6.png" alt=""> 
        </div> 
    </div> 
      
    <div id="outputDiv"> 
        <b>Output of ID's of images : </b> 
        <input id="outputvalues" type="text" value="" /> 
    </div> 
</body> 
  
</html> 

Design the structure: In this section, we will design the pre-created structure and add the drag and drop feature by adding JavaScript code.

CSS code to design the structure:

<style> 
  
    /* text align for the body */
    body { 
        text-align: center; 
    } 
      
    /* image dimension */
    img { 
        height: 200px; 
        width: 350px; 
    } 
      
    /* imagelistId styling */
    #imageListId { 
        margin: 0; 
        padding: 0; 
        list-style-type: none; 
    } 
       
    #imageListId div { 
        margin: 0 4px 4px 4px; 
        padding: 0.4em; 
        display: inline-block; 
    } 
      
    /* Output order styling */
    #outputvalues { 
        margin: 0 2px 2px 2px; 
        padding: 0.4em; 
        padding-left: 1.5em; 
        width: 250px; 
        border: 2px solid dark-green; 
        background: gray; 
    } 
       
    .listitemClass { 
        border: 1px solid #006400; 
        width: 350px; 
    } 
       
    .height { 
        height: 10px; 
    } 
</style> 

JS code to add the functionality:

<script> 
    $(function() { 
        $("#imageListId").sortable({ 
            update: function(event, ui) { 
                    getIdsOfImages(); 
                } //end update          
        }); 
    }); 
  
    function getIdsOfImages() { 
        var values = []; 
        $('.listitemClass').each(function(index) { 
            values.push($(this).attr("id") 
                        .replace("imageNo", "")); 
        }); 
        $('#outputvalues').val(values); 
    }  
</script> 

Final solution: In this section, we will combine all the above sections codes and achieve our task where you can perform the drag and drop to re-order the images in the image gallery.
