fm:Form_ChannelTree


The fm:Form_ChannelTree component generates a selectbox, populated with channels from channels in a tree indented format from your project.

This can be used for example to specify a channel in an upload form, or a list of channels and their indented children to pick when creating a gallery.

Example

<fm:Form_ChannelTree name="channel"/>
