timeline.expandFolder()

#### Availability

Flash MX 2004.

#### Usage

timeline.expandFolder(bExpand \[, bRecurseNestedParents \[, index\]\])

#### Parameters

bExpand A Boolean value that, if set to true, causes the method to expand the folder; false causes the method to collapse the folder.
bRecurseNestedParents A Boolean value that, if set to true, causes all the layers within the specified folder to be opened or closed, based on the bExpand parameter. This parameter is optional.
index A zero-based index of the folder to expand or collapse. Use -1 to apply to all layers (you also must set bRecurseNestedParents to true). This property is equivalent to the Expand All/Collapse All menu items in the Animate authoring tool. This parameter is optional.

#### Returns

Nothing.

#### Description

Method; expands or collapses the specified folder or folders. If you do not specify a layer, this method operates on the current layer.

#### Example

The following examples use this folder structure:

Folder 1 *
--layer 7
--Folder 2
----Layer 5

The following example expands Folder 1 only:

javascript

fl.getDocumentDOM().getTimeline().currentLayer = 1;

fl.getDocumentDOM().getTimeline().expandFolder(true);

The following example expands Folder 1 only (assuming that Folder 2 collapsed when Folder 1 last collapsed;
otherwise, Folder 2 appears expanded):

javascript

fl.getDocumentDOM().getTimeline().expandFolder(true, false, 0);

The following example collapses all folders in the current timeline:

fl.getDocumentDOM().getTimeline().expandFolder(false, true, -1);
