# Columns Visibility

The `columnsDropdown` option can work in conjunction with `columnsDisplay`. The rule is that as long as the user hasn't toggled a column himself, the rules you have declared in `columnsDisplay` takes precedence. Once the user toggled a column, he is in charge of columns' visibility, and the settings of `columnsDisplay` are disregarded.
