+#### Example 10.4: The Range Input
+
+Whilst working similiar to the 'text' input, the range input accepts a few more parameters. It accepts also 'min', 'max', 'step', 'list' as optional parameters.
+
+##### Example 10.4.1: Range input with max, min, step set
+
+```ruby
+form_input id: 'range-input', type: :range, min: 0, max: 100, step: 1
+```
+
+#### Example 10.4.2: Range input with corresponding datalist
+
+To use a datalist for the range input specify the 'list' parameter with the id of the provided datalist
+
+```ruby
+form_input id: 'range-input', type: :range, list: 'datalist-id'
+datalist id: 'datalist-id' do
+  option value: 10
+  option value: 20
+end
+```
