SelectionBox
( | string | label , |
| list | items
); |
make the widget very small
make `notify trigger immediately when the selected item changes
The label above the list describing what it is all about
The currently selected item or its ID, if it has one.
A selection box offers the user to select an item out of a list. Each item has a label and an optional id. When constructing the list of items, you have two way of specifying an item. Either you give a plain string, in which case the string is used both for the id and the label of the item. Or you specify a term `item( term id, string label ) or `item( term id, string label, boolean selected ), where you give an id of the form `id( any v ) where you can store an aribtrary value as id. The third argument controls whether the item is the selected item.
