+A simple slider:
+
+```php
+$renderAdminLTE->getFormInput([
+  'tag' => 'input', 
+  'type' => 'range', // <-----------
+  'min' => 0, 
+  'max' => 3, 
+  'step' => 1, 
+  'label' => 'Select 0..6',
+]);
+```
+
+#### Range with labels
+
+To add labels you need a datalist for the values and the labels to show, eg
+
+```html
+<datalist id="datalist-range">
+  <option value="0" label="no risc"></option>
+  <option value="1" label="1"></option>
+  <option value="2" label="2"></option>
+  <option value="3" label="medium"></option>
+  <option value="4" label="4"></option>
+  <option value="5" label="5"></option>
+  <option value="6" label="critical"></option>
+</datalist>
+```
+
+The id you ned to reference in the key "datalist":
+
+```php
+$renderAdminLTE->getFormInput([
+  'tag' => 'input', 
+  'type' => 'range', 
+  'min' => 0, 
+  'max' => 6, 
+  'step' => 1, 
+  'label' => 'Select 0..6',
+  'datalist' => 'datalist-range', // <-----------
+]);
+```
+
+For the datalist you need to extend your css:
+
+```css
+datalist {
+  display: flex;
+  flex-direction: column;
+  justify-content: space-between;
+  writing-mode: vertical-lr;
+  width: 100%;
+}
+```
