# UI Adaptation Modes for Rating Scale (Vanilla JS)

A Rating Scale question can change its display mode type to match the width of the used device. Two display options are available—a linear Likert scale and a drop-down menu. When the width is insufficient to fit the entire set of rate buttons, the Rating Scale question displays rate values in a drop-down menu. If you want to disable this behavior, set the [`displayMode`](/form-library/documentation/api-reference/rating-scale-question-model#displayMode) property to `"buttons"` or `"dropdown"`. Note that the `"buttons"` mode automatically generates line breaks when all rate buttons cannot fit into the available width.
