javascript - Split a nested list in to separate lists -

-

In the navigation I have a nested list.

html: 

  And lieutenant; Ul id = "big list" & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Diary product & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Milk & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Goat & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Cow & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Aromatic & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Excess smelly & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Soya & lt; / A & gt; & Lt; / Li & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Eggs & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Thing & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Pasta & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt;

desired output: 

  & lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Diary product & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Milk & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Eggs & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Thing & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Pasta & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Milk & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Goat & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Cow & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Soya & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Cow & lt; / A & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Aromatic & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "#" & gt; Excess smelly & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Li & gt; & Lt; / Ul & gt;

So far javascript: 

  $ (function () {var $ bigList = $ ('# big list'), group; while ((group = $ BigList.find ('li: LT (20)') Remove ()) Length ($ '(& lt; ul / & gt;'). Annex (group) .appendTo ('body');}} );

Here is a Bela

This simple code can do the following: 

  var myList = $ ('& lt; ul & gt;'); Var $ original list = $ ('# BigList') ; $ OriginalList.find ('li: is (li)'). Each (function () {var $ this = $ (this); $ this.clone (). AppendTo (myList) .find ('> & Gt; Li & gt; ul '). Remove ();}) $ (' body '). Lgnk (myList);

body:
