Hello
Is there a simple way to allow a selection of multiple items (zero or more) when using a dropdown ui element?
Thanks in advance
Rob
Hi Rob,
as far as i know, no. And to be honest, i can't see the benefit in doing this, if it was possible.
Regards
Stefan

Hi Stefan,
A want to be able to select more than one item in a search mask.
For example:
-
Select Search criteria:
Color: (red,green,blue,white) [Dropdown]
Size: (small, medium, large) [Dropdown]
[Start Search button]
---
So the end user can select for example "red or green" items which are "small or large" using a single selection.
regards,
Rob
Please read the Javadoc:
/**
* Web Dynpro AbstractDropDownByIndex API.
*
* Abstract base class of drop-down list classes with index based context binding.
* Represents a one-from-many selection visualized by a text field, a button and a drop-down list.
* The selected value is displayed in the text field, the list of all selectable values is displayed
* in the drop-down list which appears when the button is pressed.
* <p>
* <strong>Data binding:</strong>
* <br>
* The displayed texts and the selection are retrieved from a context.
* The context must provide a node <code>X</code> with <code>X.cardinality = 0..n</code> with an attribute
* <code>y</code> of type <code>String</code>.
* The selectable values are the values of attribute <code>y</code> of the node elements.
* The selected value is determined by the lead selection of node <code>X</code>.
* <p>
* The property <code>texts</code> must be bound to the attribute <code>y</code>.
*
* <p>This type can be called by applications using Web Dynpro, but DO NOT EXTEND OR IMPLEMENT IT!</p>

A one-from-many selection control will by definition never allow a multiple selection.
