	background-color: green;
}

tristate

Since 9.0.0 Allowing users to set the indeterminate state, in addition to the checked and unchecked states. In tristate mode, when users click on the checkbox, it will switch between checked, unchecked and indeterminate states. This is different from the default mode which has only checked and unchecked states.

<checkbox mold="tristate"></checkbox>

We provide a new API getState() return CHECKED, UNCHECKED or INDETERMINATE since ZK 9.0.0 .

State state = checkbox.getState() // CHECKED, UNCHECKED or INDETERMINATE

Indeterminate

Since 8.6.0

Indeterminate is a state that is neither checked nor unchecked.

Note: changing indeterminate will not affect the checked value, but changing checked attribute will set indeterminate to false.


    <checkbox indeterminate="true"/>

Display a checkbox like: Indeterminate.png
