I have an unordered list:
<ul id="myList"></ul>
<div id="loadMore">Load more</div>
I wish to populate this list with list items from another HTML file:
<li>One</li>
<li>Two</li>
<li>Three</li>
<li>Four</li>
<li>Five</li>
<li>Six</li>
<li>Seven</li>
<li>Eight</li>
<li>Nine</li>
<li>Ten</li>
<li>Eleven</li>
<li>Twelve</li>
<li>Thirteen</li>
<li>Fourteen</li>
<li>Fifteen</li>
I want to load the first 3 list items, then show the next 5 items when the user clicks the "load more" div:
$(document).ready(function () {
// Load the first 3 list items from another HTML file
//$('#myList').load('externalList.html li:lt(3)');
$('#myList li:lt(3)').show();
$('#loadMore').click(function () {
$('#myList li:lt(10)').show();
});
$('#showLess').click(function () {
$('#myList li').not(':lt(3)').hide();
});
});
I need help though, as I would like the "load more" to show the next 5 list items, but if there are more list items within the HTML file, to again display the "load more" div and allow users to display the next 5 items, repeating this until the entire list is displayed.
How can I best achieve this?

#showLess {
color:red;
cursor:pointer;
display:none;
}
