The flow type is a special type that allows you to use Flow Blocks in a page. Blocks are small items that work like page models but can be used for a specific field. Such a flow field can hold as many blocks as you want in a well defined order which allows you to build complex pages out of these blocks.

Each block typically renders a specific template automatically although this can be customized.

For configuration you can define which blocks are allowed by setting the flow_blocks parameter which is a comma separated list of flow blocks that are allowed. If not defined, all flow blocks become available.

The text format for flow blocks in the contents.lr file looks a bit more complex because of its nested nature, but in essence it's this:

#### name-of-flow-block ####
field-1: value 1
field-2: value 2

Because flow blocks are stored within another field the --- needs to be escaped to ----. Likewise flow blocks within flow blocks would also require an additional level by adding additional hashes for the name of the flow block:

##### nested-flow-block #####
field-1: value 1
field-2: value 2

In the template the flow type automatically renders out all the blocks within it, but the blocks can be individually accessed through the blocks attribute. Each block's attributes are the individual fields which you are free to access if so desired.

Field Usage

label = Body
type = flow
flow_blocks = text, image

Template Usage

<div class="body">
  {{ this.body }}

or more complex:

<div class="body">
  {% for item in this.body.blocks %}
    <div class="block">{{ item }}</div>
  {% endfor %}

To see how the actual blocks are rendered have a look at the main Flow Documentation which covers templating in detail.
