Showing icons on your frontend templates

The Icons can be used out of the box in templates rendered on the Wagtail admin, without any custom configuration.

Below are two possible ways of getting your svg icon to show on your custom frontend template:

1. Including individual SVG markup

You can use the svg_icon template tag as below:

{% load wagtailiconchooser_tags %}

....

{% block content %}

<div>
    {% svg_icon name=page.icon classname="your-custom-class" %}
</div>

{% endblock content %}

.....

2. Using SVG Sprites

• Add all icons to your template's context, and have them as a svg sprite. Wagtail provides a way to get all the admin icons as a svg sprite, using a view found at wagtail.admin.views.home.icons
• Add the svg sprite to your template
• use the icon template tag from wagtailadmin_tags to render your svg, which will the link with the icon from the svg sprite
• or directly render the svg to the template

We provide custom abstract page CustomIconPage, that helps you to achieve the above.

This just overrides the get_context method of the Wagtail Page class, to add the svg sprite string.

from django.db import models
from wagtail.admin.panels import FieldPanel
from wagtail.models import Page

from wagtailiconchooser.models import CustomIconPage
from wagtailiconchooser.widgets import IconChooserWidget


class MyPage(CustomIconPage, Page):
    icon = models.CharField(max_length=100, null=True, blank=True)

    content_panels = Page.content_panels + [
        FieldPanel("icon", widget=IconChooserWidget)
    ]

Your template will now have a svg sprite context object, with the key icons_svg_sprite

You can add the svg sprite anywhere in the template, and use the icon tag

{% load wagtailadmin_tags %}

....

{% block content %}

{% if icons_svg_sprite %}
{{ icons_svg_sprite|safe }}
{% endif %}

<div>
    {% icon name=page.icon %}
</div>

{% endblock content %}


.....

You can also directly render your icon without using the icon from wagtailadmin_tags template tag, sincewagtailadmin_tags is clearly meant to be used on the admin side of things.

Just replace {% icon name=page.icon %} with

{{ icons_svg_sprite|safe }}

<svg class="icon">
    <use href="#icon-{{ page.icon }}"></use>
</svg>

NOTE This approach will load all the icons added to Wagtail (using the register_icons hook) to your template. If you have registered many SVG icons, this might increase your page's loading bandwidth and might not be efficient since you might not use all the icons.

If you have a list of icons that are known, you can create a svg sprite containing only those icons, by using the function get_svg_sprite_for_icons. This can be used in a view. For example:

from django.shortcuts import render
from wagtailiconchooser.utils import get_svg_sprite_for_icons


def my_view(request):
    icons = ["some-icon", "some-other-icon", ...]
    svg_sprite = get_svg_sprite_for_icons(icons)

    context = {
        "svg_sprite": svg_sprite
    }

    return render(request, "template.html", context=context)

In your template.html you will have access to the svg_sprite context, and you can render and use as below:

<div>
    {{ svg_sprite|safe }}
</div>

<svg class="icon">
    <use href="#icon-some-icon"></use>
</svg>

<svg class="icon">
    <use href="#icon-some-other-icon"></use>
</svg>
