Question

I want a button that says, “Send a private message”. And when that button is clicked, a list of friends drops down.

I don’t want to use heavy JQuery menu plugins, because they’re too heavy and are made for navigation.

Answer 1

I would suggest simply using a hidden div element, which you populate with the required data either in the click event handler on the button, or when the page loads. You can then use the standard jQuery functions such as slideDown or show to make the div visible:

$("#yourButton").click(function() {
    $("#hiddenDiv").slideDown();
});

That way, you don’t need to include any JavaScript library files except the base jQuery file.
