! Introduction

The scrollable widget wraps its content in a scrollable frame. The user can scroll the contents with the mouse or with touch gestures. Code can use the [[WidgetMessage: tm-scroll]] to programmatically scroll specific DOM nodes into view.

! Content and Attributes

The content of the `<$scrollable>` widget is displayed within a pair of wrapper DIVs. If the inner DIV is larger then it scrolls within the outer one. CSS is used to specify the size of the outer wrapper.

|!Attribute |!Description |
|class |The CSS class(es) to be applied to the outer DIV |
|fallthrough |See below |

If a scrollable widget can't handle the `tm-scroll` message because the inner DIV fits within the outer DIV, then by default the message falls through to the parent widget. Setting the ''fallthrough'' attribute to `no` prevents this behaviour.

! Examples

This example requires the following CSS definitions from [[$:/_tw5.com-styles]]:

```
.tc-scrollable-demo {
	border: 1px solid <<colour message-border>>;
	background-color: <<colour message-background>>;
	padding: 1em;
	height: 400px;
	position: relative;
}
```

This wiki text shows how to display a list within the scrollable widget:

<<wikitext-example-without-html "<$scrollable class='tc-scrollable-demo'>
<$list filter='[!is[system]]'>

<$view field='title'/>: <$list filter='[all[current]links[]sort[title]]' storyview='pop'>
<$link><$view field='title'/></$link>
</$list>

</$list>
</$scrollable>
