Tree supports 3-states checkboxes: checked, not checked, partially checked. Moreover checkbox can be disabled:

tree.disableCheckbox(id,1);

In order to use combination [checked, not checked,ignored] instead of [checked, not checked, partially checked], you can change iconCheckGray.gif to the necessary:

tree.checkArray = new Array("iconUncheckAll.gif","iconCheckAll.gif","iconCheckGray.gif","iconUncheckDis.gif","iconCheckDis.gif","iconCheckDis.gif");

tree.enableCheckBoxes(1);

tree.enableThreeStateCheckboxes(1);

tree.enableSmartCheckboxes(0);
