This sample demonstrates the grouping functionalities of the MultiSelect in checkbox mode. Clicking the checkbox in group will select all the items grouped under it. Click the MultiSelect element and then type the character in the search box. It will display the filtered list items based on the typed characters and then select the multiple values through the checkbox.
The MultiSelect has built-in support to select the multiple values through the checkbox, when the mode property
is set to CheckBox. To perform the checkbox feature in MultiSelect, the CheckBoxSelection module
should be injected in the application end.
