A standard browser combobox input control (single line listbox that expands when clicked upon)
e.g. (exact style is dependent on any applied CSS)
Any Options List element attached is considered the name of the variable to use for the data for the control.
This is a single line version of the listbox control (see for other options), when an item is selected, the description, hidden key and list position are stored in the internal memory store as <name>.selectedValue, <name>.selectedKey and <name>.selected_id respectively, allowing these to be used as parameters in subsequent model invocations. (NOTE: selected_id is now deprecated). Where <name> is the name of the control.
If the variable <name>.initialValue is set when the data is loaded, then this will be used as the default selected value. Note however this is the VALUE, i.e. the item on the bottom of the graph elements which are loaded into the control, also it needs to be set before the data is loaded, so if both are in an Action Graph, the Store of the the initialValue needs to be processed before that of the data load.
Specific styling/look and feel may be achieved by the use of CSS.
