sap.m.Select: start with a blank selection input element

Question

When using a data aggregation on sap.m.Select, the first entry is always selected. Here's a link to the SDK's preview.

Example code from my app

new sap.m.Select("id-names", {
    width: '100%',
}).bindAggregation("items", "data>/trip/names", new sap.ui.core.Item({
    text: "{data>Name}"
}));

There is a parameter called selectedKey on the constructor to change this to another index. What I want is the select to be blank, because I want to force my users to make a choice, not blandly accept the first entry in the list.

I could force an blank entry in my aggregation data>/trip/names but that would pollute my list.

Is there a better way to achieve this?

Answer 1

Since the OpenUI5 version 1.34, you can set the forceSelection property to false.

The forceSelection property indicates whether the selection is restricted to one of the items in the list. The default value is true (which means, if the selection is not set, the first item in the dropdown list is selected).

When to set it to false?

If you do not want a default item to be pre selected.
