Hideable: Boolean;
The Hideable property determines whether column can be hidden.
Use JSON or the setHideable method to set the property value and the getHideable method to get the property value.
Executing the example requires the SimpleTreeList component with the Tree identifier (see Example of Creating the SimpleTreeList Component).
// Get title caps = Tree.getCaptions(); cap = caps.getCaptions()[0]; // Disable changing column visibility cap.setHideable(false);
After executing the example it is disabled to change column visibility.
