multiple conditions in if statement Go templates

You need to use function and, like:

{{ if and .condition1 .condition2 }}
<!-- SHOW SOMETHING -->
{{ end }}

Here's an working example: https://play.golang.org/p/g_itE5ggCM

{{ if and (eq .var1 "8") (eq .var2 "9") (eq .var "10") }}
<!-- SHOW SOMETHING -->
{{ end }}

The parenthesis make the trick
