# Range Slider

Adds a possibility to use Range Slider as a form field for your form. It can be of two types: *single* and *double.* For instance, this is how it looks like in *single* mode:

🏆 **PRO FUNCTIONALITY**: In addition to the main variable that holds a value itself (or two values separated by dash sign), this Option also has these special vars:

```
{option_slug_from}
{option_slug_to}
```

These variables hold left and right values chosen. *From* is for the left value and *to* is for the right. Obviously, they are used in *double* mode.
