Parsley Index

_index
When looping through a content model with an each loop, you can use variable_name._index to get the current count of how many times you have run through the each loop. _index begins counting from 0. To start counting at 1 use _num instead.
1
<div class="row">
2
{{ each team_members as member }}
3
{{ if {member._index} % 3 == 0 }} (** Checks for every third loop, can be used to end and stop rows when using fixed width columns in a grid  **)

</div><div class="row">

{{ end-if }}

truepath() can be used in each loops as well, for example {{ truepath(this.zuid) }} or {{ this.zuid.truepath() }} and you can assign it to a Parsley variable as well.

{{each articles as art limit 5}}
2
    {{art.zuid}} <br>
