c++ web application with drag & drop linked lists

Cross plattform (Linux, Windows) 32/64bit c++ web application using wt toolkit ([login to view URL]). The application runs on a server (Windows/Linux, 32/64 bit). The output is on a web browser (IE11, Firefox or Safari). The application has 4 HTML cells (at the top and the bottom and two in the middle) in which the server can push (and update anytime) html5 content. Then we have 2 toolbars and a splitter window where the user can adjust the size. The main part contains two linked lists where items can be drag & dropped (drop must be possible to each position including adding at the top and appending at the bottom. Here some ideas ([login to view URL] or [login to view URL]). Note that content of cell element could be any htmls5 content. The items in the lists are stored in the server in an array (struct) where we have the html5 code of the list cell element which can be a combination of text, pictures and buttons with links and the a attribute flag of the cell element. Attributes of cell elements could be at least normal or locked and selected or not. If locked a drag out will make a copy otherwise we move when dropped. Dropping before a locked item should not be possible. Full list could be set as read/copy only. Drag out of locked items or read/copy only lists is always possible. The html cell of the lists could have dynamic cell height depending on the html5 content in the cell elements. Server can push new html content to a cell element with different height anytime and change attribute to locked anytime. If selected there should be drawn a colored frame around the html cell element. If there are more elements in a list as the browser could display there should be a scrollbar on the right side. The hight of the html list is dynamic depending on the size of the browser. rest has fixed hight. Width is dynamic depending on browser window width. Locked elements can be selected. No need to mark them as locked only always drag out will copy instead of move. If <ctrl>-key is pressed we drop a copy in any case and never a move of a list element. There should be the possibility to link the 2 html lists (left and right) that only one cell in both lists is selected. When several browser instances are connected the changes (drag & drop in one browser) should be pushed to all connected browsers that they stay in sync. A later in the server included task will change content of the html cell and push that to all connected browsers or will delete and/or add html5 cell items or change the attributes. There should be some test functions to simulate that in the server and adding some test content. VC10 project files (sln, vcxproj) has to be provided for Windows with c++ code and all libraries to compile. Watch attached picture. Ask if you have questions. This is a start. Project would be extended if successful.
