I have a span element and it has a backgorund image search, on click of search button I open menu. I don't need a button beside my search button, so I added data-toggle=dropdown to my span. Dropdown menu is opened when I click with mouse, but menu is not opened when i get focus to span and press enter key on it.

Here it is reproducible

You need to make some changes in the HTML. move the span inside the button tag and remove the data-toggle="dropdown" attribute form the span and add it to the button.

From

<button class="btn btn-primary dropdown-toggle" type="button" >Dropdown Example</button>
    <span tabindex=0 class="caret" data-toggle="dropdown"></span>

To

 <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown Example
    <span tabindex=0 class="caret" data-toggle="dropdown"></span></button>

Here is the full code

<!DOCTYPE html>
<html>
<head>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Dropdowns</h2>
  <p>The .dropdown class is used to indicate a dropdown menu.</p>
  <p>Use the .dropdown-menu class to actually build the dropdown menu.</p>
  <p>To open the dropdown menu, use a button or a link with a class of .dropdown-toggle and data-toggle="dropdown".</p>                                          
  <div class="dropdown">
    <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown Example
    <span tabindex=0 class="caret" data-toggle="dropdown"></span></button>
    <ul class="dropdown-menu" role="menu">
      <li><a href="#">HTML</a></li>
      <li><a href="#">CSS</a></li>
      <li><a href="#">JavaScript</a></li>
    </ul>
