DropdownByIndex and empty element

[Former Member]

Hi Experts,

I have a checkbox & a dropdownbyindex in my layout. When I select a checkbox, its corresponding values appear in a dropdown.

Properties of the context node:

Cardinality - 1..n

Selection - 0..n

I want an empty line in the dropdown. For e.g. If I select checkbox C1 which has corresponding values D1,D2 & D3, my dropdown should list 4 values - an empty element, D1, D2 and D3.

But I am not getting an empty element in the dropdown. Can you please help?

Thanks.

Suppose that the internal table 'ITAB' contains the values D1,D2,D3 which you bind to the node.

So add 1 more statement.

INSERT INITIAL LINE INTO ITAB INDEX 1.

This will show an empty element as required.

Hi Hitesh,

It works.

But not sure if the best way to achieve this would be through setting the correct cardinality.

Thanks.

Well, an empty row is nothing but another element. So, you need to insert it if the need is to have an empty row.

I don't see another way of accomplishing the requirement.
