Hi, guys,

Thank you for clicking this ticket,

On Front Matter

```auto
---
layout: archive

lang: en

ref:
- xl430-w250
- xc430-w150
---

```

Mark Down

```auto
{% for sec in page.ref %}

{{ sec }} <-- This works 

{{ sec[0] }} <-- This does not work.. 

{% endfor %}

```

Is there any way to access the index of the particular array?

Thank you 🙂

When using the Liquid `{% for %}` tag, you have access to the loop index via the `forloop` object.  
The index of the current item iterated can output by `{{ forloop.index }}`  
(_Note: It starts with 1 instead of 0_).

Hi, Thank you for your advice.

Unfortunately, it does not work…

Front Matter

```auto
layout: archive
ref:
  - ref1: "xl430-w250"
  - ref2: "xc430-w150"
  - ref3: "xh430-w210"

```

Markdown

```auto
{% for reference in page.ref %}

{{ reference.index[1] }} 

{{ reference.index1 }}

{{ reference.index 1 }}

{{ reference.1 }}

{% endfor %}

```

😱

Regarding the first section

```auto
---
layout: archive

lang: en

ref:
- xl430-w250
- xc430-w150
---

```

If you want to use `[0]` index then don’t do it on a for loop.

Here you can get the first element of the array

```auto
{{ page.ref[0] }}

```

Regarding the 2nd case, you defined a list of hashes when I think you just want a hash. Note lack of leading dashes

```auto
ref:
  ref1: "xl430-w250"
  ref2: "xc430-w150"
  ref3: "xh430-w210"

```

Then can do

```auto
{% for r in page.ref %}
- Key {{ r[0] }} - Value {{ r[1] }}
{% endfor %}

```

The zero and one indexes are to unpack the r item…

As your frontmatter will be converted from YAML to a Ruby object stored like this.

```ruby
{ "ref1": "x1430-w250"}

```

And when you use the for loop it becomes an array (or a tuple) of exactly two elements.

```ruby
["ref1", "x1430-w250"]

```

I think you misunderstood my comment.  
I suggested that you use `{{ forloop.index }}` explicitly.

```auto
---
lang: en
ref:
- xl430-w250
- xc430-w150
---

{% for item in page.ref %}
  {{ forloop.index }}. {{ item }}
{% endfor %}

```
