I have tried appending two li tags here
var view = d3.select('#contextMenuNode')
view.html(<li><a id="selectLinked1" tabindex="-1" href=#>View A</a></li> <li><a id="selectLinked2" tabindex="-1" href=#>View B</a></li>
)

Check out this.
$(document).ready(function() {
//Show contextmenu:
$(document).contextmenu(function(e) {
//Get window size:
var winWidth = $(document).width();
var winHeight = $(document).height();
//Get pointer position:
var posX = e.pageX;
var posY = e.pageY;
//Get contextmenu size:
var menuWidth = $(".contextmenu").width();
var menuHeight = $(".contextmenu").height();
//Security margin:
var secMargin = 10;
//Prevent page overflow:
if (posX + menuWidth + secMargin >= winWidth &&
posY + menuHeight + secMargin >= winHeight) {
//Case 1: right-bottom overflow:
posLeft = posX - menuWidth - secMargin + "px";
posTop = posY - menuHeight - secMargin + "px";
} else if (posX + menuWidth + secMargin >= winWidth) {
//Case 2: right overflow:
posLeft = posX - menuWidth - secMargin + "px";
posTop = posY + secMargin + "px";
} else if (posY + menuHeight + secMargin >= winHeight) {
//Case 3: bottom overflow:
posLeft = posX + secMargin + "px";
posTop = posY - menuHeight - secMargin + "px";
} else {
//Case 4: default values:
posLeft = posX + secMargin + "px";
posTop = posY + secMargin + "px";
};
//Display contextmenu:
$(".contextmenu").css({
"left": posLeft,
"top": posTop
}).show();
//Prevent browser default contextmenu.
return false;
});
//Hide contextmenu:
$(document).click(function() {
$(".contextmenu").hide();
});
});
