XML name of the component: lookupPickerField.

The component is implemented for Web Client and Desktop Client.

In fact, LookupPickerField is a hybrid of LookupField and PickerField. Thus it has the same features except the default list of actions added when determining the component in XML: for LookupPickerField these are lookup lookupBtn and open openBtn actions.

Below is an example of using LookupPickerField to select a value of the colour reference attribute of the Car entity:

<dsContext>
    <datasource id="carDs" class="com.company.sample.entity.Car" view="_local"/>
    <collectionDatasource id="coloursDs" class="com.company.sample.entity.Colour" view="_local">
        <query>select c from sample$Colour c</query>
    </collectionDatasource>
</dsContext>
<layout>
    <lookupPickerField datasource="carDs" property="colour" optionsDatasource="coloursDs"/>
