Parsley Index
This index collects all Parsley syntax and methods.
_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  **)

eventCategory: text required Typically the object that was interacted with (e.g. 'Video')
eventAction:text required The type of interaction (e.g. 'play')
eventLabel:*text* optional Useful for categorizing events (e.g. 'Fall Campaign')
eventValue:*integer* optional A numeric value associated with the event (e.g. 42)
