Selector Creator

Author or modify a Datex Studio selector (configurationTypeId=7) on a branch — the platform's dropdown / autocomplete control. Selectors define an option list backed by a datasource, a display-label expression over each option, and a built-in full-text search box that forwards typed input into the backing datasource. They mount inside form fields, hub filter dropdowns, and grid filter cells; they don't render standalone.
