django template view nested list

Question

i made a nested list and from that id like to make a table in my template

list looks something like

ground_skills_available = [[category1, [skill1, skill2, skill3]], [category1, [skill1, skill2]]]

Now i want to list it that you got category with below the items, next category and other items. Problem is, i have no clue about hot to show only category, instead of category +all items, since you cant seem to use the index of a list?

Can someone please help me out?

<table>
    {% for categories in ground_skills_available %}
        {% for category in categories %}
        <tr>
            <td>{{ category }}</td>
        </tr>
            {% for skill in category %}
            <tr>
                <td>{{ skill.name }}</td>
            </tr>
            {% endfor %}
        {% endfor %}
{% endfor %}

Change your outer loop to

{% for category, skills in ground_skills_available %}

This technique is described in the Django for loop docs.

On the first iteration of the loop, this will take the list [category1, [skill1, skill2, skill3], and assign

category = category1
skills = [skill1, skill2, skill3]

You can then display {{ category }}, and loop through skills.

Putting that together, you have:

<table>
    {% for category, skills in ground_skills_available %}
        <tr>
            <td>{{ category }}</td>
        </tr>
        {% for skill in skills %}
        <tr>
            <td>{{ skill.name }}</td>
        </tr>
        {% endfor %}
    {% endfor %}
</table>

{% if forloop.index == 1 %} ... some code ... {% endif %}

or

{% if forloop.index0 == 0 %} ... some code ... {% endif %}

Expectation:

{% for categories in ground_skills_available %}

    {% for category in categories %}
    {% if forloop.first %}
    <tr>
        <td>{{ category }}</td>
    </tr>
    {% else %}
        {% for skill in category %}
        <tr>
            <td>{{ skill.name }}</td>
        </tr>
        {% endfor %}
     {% endif %}
    {% endfor %}

{% endfor %}
