First of all, I would like to express my gratitude for such a wonderful library. I am glad that there is such functionality in Vaadin. I have two questions, first, when I open a view where I give users Roles and Permissions I have the items marked "checked" in the right column. How can I cancel this functionality? Second question, can I remove the Select All and Cancel All buttons. Because I'm afraid someone will accidentally click and move the items.

You can clear "checked" in the select column by

select.clearTicks(ColType.RIGHT);

> Second question, can I remove the Select All and Cancel All buttons. Because I'm afraid someone will accidentally click and move the items.

There is no API for that, but there is buttonless variant and you can set picking by single click, perhaps that is what you want:

select.addThemeVariants(TwinColSelectVariant.NO_BUTTONS);

select.setPickMode(PickMode.SINGLE);
