It would be great if selecting text on a webpage showed some options like copy, paste, or share. A selection menu accomplishes this. Basically, it is a GUI that displays in response to user activity, such as text selection. A selection menu provides a different range of options that you can access just by clicking them. Typically, the accessible options are actions associated with the selected object. You may familiar with different types of selection menus that will appear when you select some text on any website. In this article, we will create a custom/selection menu that floats right above the selected text. 


<div class="menu">
    <i class="fa fa-copy fa-2x"></i>
    <i class="fa fa-highlighter fa-2x"></i>

Approach: We have created a very simple structure consisting of 2 div’s, the first one has some dummy text to select, and inside the first div second div is present. The Second div is our custom/selection menu which will appear on text selection. To create different options for the menu, we have used font-awesome icons which will also give our menu a visual pleasure. You can add as many options as you want to your selection menu. But here we have added only two options, the first is copy and the second is highlight.

Now, Let’s understand the JavaScript part. First, we get the selected string with the help of document.getSelection(). If the selected string is not empty then we get the position of the first div via getBoundingClientRect() and place it in the rect variable. Using rect, we calculate and assign the top and left positions of the selection menu (second div). This way, the selection menu is placed a little above the selected area and centered horizontally. The selection menu control will show on the screen if we choose some of the example text on the page at this time.

        In today’s digital world, when there are thousands of online platforms
        (maybe more than that!) available over the web, it becomes quite
        difficult for students to opt for a quality, relevant and reliable
        platform for themselves. Meanwhile, as Computer Science is a very vast
        field hence students are required to find an appropriate platform that
        can fulfill all their needs such as – Tutorials & Courses, Placement
        Preparation, Interview Experiences, and various others. And with the
        same concern, GeeksforGeeks comes in the picture – a one-stop
        destination for all Computer Science students!!

      <div id="mypopup" class="popup">
        <div class="popup-content">
