After the checkbox, add a hidden input box with the same name as the checkbox and value "false", forcing struts to reset the property value of the checkbox
In general, Boolean variables are used in Actionform to represent a checkbox because it is either not selected or is selected.

The Multibox tag generates a check box on a Web page, but it functions as a checkbox.
The difference is that the check box is represented by an array in the Actionform where the check box is located.
Therefore, in general, the recommended use of Multibox.

<!--
Size is 1, only one option is displayed at the same time.
There is also a multiple property that, when True, allows multiple selections for the select list. The user can drag through the mouse or hold down the CTRL key to select multiple selections.
When the Multiple property is true, the corresponding property in Actionform should be an array type to assign to it the user-selected multiple values at the same time.
