Solved: mouseout is not working as expected

I'm dynamically generating a list of checkboxes, I want this to dissapear as soon as I mouse out, but it dissapears
when I move my mouse out of Fldsbutt
<div class="container" id = "container"> 
        <div class="form-group">         
                <label for="selfile" class="col-sm-2 control-label">  Select File </label>  
                        
                <?php
                
                    $options = generate_files();
                    echo '<select id="selfile" name="selfile">'.$options.'</select>';                    	        
                ?>
              
        </div>
