<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js"></script>I have this Treeview and I want to make it fully support right-to-left (RTL) display. I have already included a Bootstrap CSS link to support Arabic RTL, but it did not succeed in making it support right-to-left display. Note: I also want the outer ul elements (not the inner ones that appear when the Treeview is collapsed) to be included in a Bootstrap class called "timeline" and the outer ul elements should appear as shown in this image.
Solution
Try this :
$.fn.extend({
treed: function (o) {
var openedClass = 'fa-minus-circle';
var closedClass = 'fa-plus-circle';
if (typeof o != 'undefined'){
if (typeof o.openedClass != 'undefined'){
openedClass = o.openedClass;
}
if (typeof o.closedClass != 'undefined'){
closedClass = o.closedClass;
}
};
//initialize each of the top levels
var tree = $(this);
tree.addClass("tree");
tree.find('li').has("ul").each(function () {
var branch = $(this); //li with children ul
branch.prepend("<i class='indicator fas " + closedClass + "'></i>");
branch.addClass('branch');
branch.on('click', function (e) {
if (this == e.target) {
var icon = $(this).children('i:first');
icon.toggleClass(openedClass + " " + closedClass);
$(this).append("<div class='loading'><span class='fa fa-spinner fa-spin'</span></div>");
setTimeout(()=>{
$(this).find('.loading').remove();
$(this).children().children().slideToggle(400);
}, 400)
}
})
branch.children().children().toggle();
});
//fire event from the dynamically added icon
tree.find('.branch .indicator').each(function(){
$(this).on('click', function () {
$(this).closest('li').click();
});
});
//fire event to open branch if the li contains an anchor instead of text
tree.find('.branch>a').each(function () {
$(this).on('click', function (e) {
$(this).closest('li').click();
e.preventDefault();
});
});
//fire event to open branch if the li contains a button instead of text
tree.find('.branch>button').each(function () {
$(this).on('click', function (e) {
$(this).closest('li').click();
e.preventDefault();
});
});
}
});
//Initialization of treeviews

$.fn.extend({

var openedClass = 'fa-minus-circle';

}
if (typeof o.closedClass != 'undefined'){
closedClass = o.closedClass;
}
};

tree.addClass("tree");
tree.find('li').has("ul").each(function () {

setTimeout(()=>{
$(this).find('.loading').remove();
$(this).children().children().slideToggle(400);
}, 400)
} else {
$(this).children().children().slideToggle(400);
}
}
})
branch.children().children().toggle();
});
//fire event from the dynamically added icon
tree.find('.branch .indicator').each(function(){
$(this).on('click', function () {
