i am making a tree with the help javascript and jquery .
I the tree there are four buttons that are being provided to change the indentation of the nodes.
let me explain the buttons.
-> left indent if i select a child and click on it should make the particular child to a next level child.
for ex: a is the root that have two children b,c at same level if i select c and click on the left indent c should become the child of b.
result will be a has two level children b at one level and c is the child of b .
<- right indent if i select a child of child and click on this right indent than it should become same level child.
for ex: in the above case i have made c as child of b whose root is a now i want that c should again be at the same level of b than i select c and click right indent.
*Result*a has two children b,c at the same level.
if any of the selected item have further childs than it should follow it automatically. I hope i am able to visualize my scenario. how to proceed with this no clue.
in my markup there is only one div tag which is containing every thing and a button that calls the function 'getuperparent()' I am pasting my code to get a feel of how things are going on.

If I understand correctly, you want to do something like indent / unindent in MS Word's "outline mode". So, in this situation:
- a
- b
- c
- d
When you press "indent" on "b", the situation should be:
- a
- b
- c
- d
If you then press "unindent" on "c", the situation is:
- a
- b
- c
- d
You can do it this way (assuming the selected element has class "selected" and there is only one such element at any time):
function indent() {
var $element = $('.selected'),
$newParent = $element.prev();
if ($newParent.length) {
$element.appendTo($newParent); // I'm pretty sure this moves the element, might have to remove() as well
}
}
function unIndent() {
var $element = $('.selected'),
$parent = $element.parent();
$element.insertAfter($parent); // I'm pretty sure this moves the element, might have to remove() as well
}
This will also move any children of the moved node, that is, they will remain under their (moved) parent.
EDIT: as a bonus, here's the moveUp and moveDown functions:
function moveUp() {
var $element = $('.selected'),
$previous = $element.prev();
if ($previous.length) {
$element.insertBefore($previous);
}
}
function moveDown() {
var $element = $('.selected'),
$next = $element.next();
if ($next.length) {
$element.insertAfter($next);
}
}
Obviously some redundancy could be removed here, which I'll leave as "an exercise to the reader" ;)
