Question

I have a sorted dictionary that contains sort options:

sort_options = SortedDict([
    ("importance" , ("Importance" , "warning-sign")),
    ("effort" , ("Effort" , "wrench" , "effort")),
    ("time_estimate" , ("Time Estimate" , "time")),
    ("date_last_completed" , ("Date Last Completed" , "calendar")),
])  

I’m displaying these options in my template:

{% for key, icon in sort_options.items %}<!-- Sort Options -->
    <a class="btn btn-info" href={{ request.path }}?key={{ key }}&orientation=desc><i class="icon-{{ icon.1 }} icon-large"></i></a>
{% endfor %}

I need to define the 4 sort options, but I only want to display the first 3 (the remaining options are used elsewhere). I also anticipate adding other sort options that I won’t need to be displayed. I could write an if statement with a forloop counter to prevent the last option from displaying, but this seems wasteful.

I found this filter but I’m not sure how to combine it with the forloop that needs both the key and the icon data.

How can I write a django template for loop that runs on a dictionary and only loops X number of times?

Similar to Joe’s answer, but there’s actually a built-in filter slice that’ll do this for you:

{% for key, icon in sort_options.items|slice:":3" %}
