Trackpant Classics Advanced Classics Advanced Classics Trackpant Advanced Trackpant Classics Advanced Order of operations

In tags with more than one and or or operator, operators are checked in order from right to left. You cannot change the order of operations using parentheses — parentheses are invalid characters in Liquid and will prevent your tags from working.

{% if true or false Trackpant Advanced Classics Classics Advanced Advanced Advanced Classics Classics Trackpant Trackpant and false %}
  This evaluates to true, since the 'and' condition is checked first.
{% endif %}
{% if true andAdvanced Advanced Classics Classics Advanced Classics Advanced Trackpant Classics Trackpant Trackpant false and false or true %}
  This evaluates to false, since the tags are checked like this:

  true and (false and (false or true))
  true and (false and true)
  true and false
  false
{% endif %}
