_**This is a work in progress.**_
# Description
User cannot visually design a layout of dashboard widgets. This layout tool will allow a user to deploy dashboard widgets by drag & drop.
There are several requirements that this layout tool should satisfy.
1. Change the order of widgets in a group by drag & drop.
2. Change the size of a widget.
3. Pad [`ui_spacer` widgets](https://github.com/node-red/node-red-dashboard/tree/spacedout) when blank spaces are needed.
4. Move a widget from one group to the another.
5. (optional) Change the size of a group.
# User interface
To show the layout tool of dashboard, Add `layout` button on the tab menu.

When a user clicks the `layout` button, the window of a layout tool will appear. It should look like the maximized window of function node.
After a user adjusts the layout on the window:
- If the user clicks `Done` button:
- inserts ui_spacer widget if necessary.
- updates the layout of sidebar and workspace.
- If the user clicks `Cancel` button, the change will be discarded.

# Future discussion
- Add a node on the layout tool.
- Add/remove a group.
