This control is only available for Query forms.
The Multiselect Combo control lets you select from a drop down list records related to a single attribute, as search criteria for a query.
The control displays all the records found in the database for the selected entity, and you can select one or more of those records.
The Multiselect Combo also displays a search box where you can type the name of the record you want to find. As you type, Bizagi displays the records that match the text you enter, within any place of the record (not only the beginning). For example, if you type "wer" and a record called "Flower" exists, this record appears in the results list.
•You can use the Multiselect Combo control for Parameter, Stakeholder and System entities.
•This control cannot search in master entities.
•The Multiselect Combo control is not available in the Work Portal for Experience data searches.
