The range element allows the CMS user to select a value between a given minimum and maximum amount.
When the range element is added to a section, besides the name and tooltip there are 3 extra values that need to be provided.
minimum value is the lowest possible value of the range slider.
maximum value is the highest possible value of the range slider.
step is the size of the step the range slider will provide. If for example set on 0.2, the value can be increased or decreased by 0.2.
