Value Help as a Dropdown List

You can configure value help as a dropdown list.

Note:

For information about SAP Fiori elements for OData V4, see Value Help as a Dropdown List.

If the entity set of a value help has a fairly stable number of instances, you can render an input field with a value help and dropdown list box (sap.m.ComboBox and in cases of multi selection a sap.m.MultiComboBox) using the metadata extension sap:semantics='fixed-values' on the entity set level and the sap:value-list='fixed-values' on the property level.

In the following sample code, the product category is implemented as a dropdown list box:

Sample Code:

$metadata

<EntityType Name="SMART_C_ProductType" sap:label="Product" sap:content-version="1">
    <Key>
        ...
    </Key>
    ...
    <Property 
        Name="ProductCategory" 
        Type="Edm.String" 
        Nullable="false" 
        MaxLength="40" 
        sap:label="Category" 
        sap:value-list="fixed-values" />
    ...
</EntityType>

<EntityContainer 
    Name="SMART_PROD_MAN_Entities" 
    m:IsDefaultEntityContainer="true" 
    sap:supported-formats="atom json xlsx">
    ...
    <EntitySet 
        Name="SEPMRA_I_ProductCategory" 
        EntityType="SMART_PROD_MAN.SEPMRA_I_ProductCategoryType"
        sap:creatable="false" 
        sap:updatable="false" 
        sap:deletable="false" 
        sap:searchable="true" 
        sap:content-version="1" 
        sap:semantics="fixed-values" />
</EntityContainer>

The following screenshot shows the Category field displayed as a dropdown list box:
