Hi All,
Can anyone please give me an example of how to make a list of items that can be rearranged via drag and drop or buttons and the new order retrieved? Lou -- Louis LaBrunda Keystone Software Corp.

Hi Louis,
I use jQuery UI sortable() [1] for this. You need to add the JQUiDeploymentLibrary library to your application (or link the to the files). MyComponent>>renderContentOn: html html div "snip" script: (self createSortableOn: html) "snip" MyComponent>>createSortableOn: html ^(((html jQuery id: self elementId) find: '.' , self containerCssClass , ':first') sortable) placeholder: 'placeholder'; handle: '.sort-handle'; onStart: ((JSStream on: 'ui.placeholder.height(ui.item.height());') asFunction: #('e' 'ui')); onUpdate: (self createSortableUpdateScriptOn: html); yourself MyComponent>>createSortableUpdateScriptOn: html ^html jQuery post callback: [:v | self reorderChildrenWithSequence: (v subStrings: ',')] value: (((html jQuery id: self elementId) find: '.' , self containerCssClass, ':first') call: 'sortable' with: 'toArray') Each sortable DOM element has an id attribute that is what the sortable("toArray") uses to get the id of each (it is also configurable), then with that collection of IDs look for them in my model: reorderChildrenWithSequence: anOrderedCollection self children: (anOrderedCollection collect: [:each | self children detect: [:one | one elementId = each]]). self model children: (self children collect: [:each | each model]) Also I use a placeholder while the dragging begins, you can remove the onStart: part if you're not interested in it. I hope this helps you get started. Best regards, [1] https://jqueryui.com/sortable/ ps: My case is a little more complicated as I can sort at arbitrary depth (but only within the same level of depth), but it's a single component that recursively builds a tree of components. You can replace the ((html jQuery id: self elementId) find: '.' , self containerCssClass , ':first') by your jQuery instance. Esteban A.

Check out the examples using jQueryUI.
After loading Seaside in your image, you can find them at http://localhost:8080/javascript/jquery-ui cheers Johan
