Drag and drop with jQuery UI Sortable | Simon Battersby
Last September I wrote a bespoke e-commerce solution for my wife’s website, including all the accompanying admin screens. One admin screen allows the amendment of the display order of items in a particular category. It was, if I’m honest, a bit clunky, as you had to type in the display order as a number, and then refresh the screen to see what the resultant re-order looked like. In response to repeated requests of “Can’t you make it drag and drop…?” I switched from responding with hollow laughter and actually had a look at how this might be done. And surprisingly, it was pretty straightforward. Setting up the database I already had a database with a table called items, each of which had a unique ID field and another field called Display_Order. Displaying the items on the “Maintain Display Order” admin page I started off just setting up the page to display all the items. <li id="ID_1">... Then, I added a bit of css to make my list into two columns of images to match the real page layout.
Bootstrap Form Builder
Rendered source of your form: About Created By Adam Moore (@minikomi) to help take the stress out of writing all that markup to get bootstrap forms together. The original version of this was a big jQuery spaghetti mess, so as of March 2013 it has been rewritten using backbone.js and takes advantage of underscore.js templates. If you have a problem, or want a specific snippet added please check out the github project. Note, this is only a simple tool so I'm not that keen on adding many features (eg. saving/exporting forms, embedding forms etc.). Adding snippets is quite simple now (due to the rewrite!)

Per Javascript: Bequemes Drag & Drop für Webanwendungen
Anhand einer leicht anwendbaren Drag & Drop-Library und einer konkreten Aufgabe stellen wir Ihnen vor, wie Sie Drag & Drop effektiv und sinnvoll auf Ihrer Website einsetzen. Innerhalb des Admin-Bereichs einer Anwendung sollen einem Benutzer Rechte zugeordnet werden. Dazu sind zwei Spalten vorgesehen: Eine enthält die bereits zugewiesenen Berechtigungen, während die andere alle Rechte enthält, die der Nutzer nicht hat. Per Drag & Drop sollen die Rechte ganz einfach von einer Spalte in die andere verschoben werden können. Die beiden Spalten sind als ungeordnete Listen realisiert. Die <li>-Elementen stellen die einzelnen Rechte dar. Im onload-Event des aktuellen Fensters passiert der grundlegende Aufbau des Drag & Drop-Schemas. Das System identifiziert die beiden Rechte-Spalten anhand ihrer unterschiedlichen Id in pos_col und neg_col. Nachricht ans Backend schicken pos_col(3,9):neg_col(1,2,4,5,6,7,8) <html><head><title>Rechteverwaltung</title> body { margin: 10px 10px 10px 10px;
