### Slider Tool Options

**Schema ID**: The unique ID assigned to the tool.

**Title**: The name of your Slider classification.

**Description**: Optional text shown to labelers in the labeling editor.

**Required**: If you enable this toggle, labelers will be required to answer this field before saving.

**Min Value**: The lowest numeric value labelers can select.

**Max Value**: The highest numeric value labelers can select.

**Step Size**: The interval between selectable slider values. For example, a step size of `1` allows whole numbers, while `0.5` allows half-step values.

**Min Label**: Optional text shown at the low end of the slider.

**Max Label**: Optional text shown at the high end of the slider.

**Frame-specific**: If you enable this toggle, the answer to this classification will only be valid for one frame in videos and multi-frame images/DICOMs instead of the whole asset.

**Data-specific**: If you enable this toggle, the answer to this classification will be stored separately for each data item in grouped assets.

**Multiple**: If enabled, annotators can answer this classification multiple times.

Slider answers are saved and exported as numeric values.

Once you have selected your options, click on *Save* at the bottom to save your changes.
