Two things, for INSTALL_APPS it should only be myproject.app
Django will find the templatetags directory in your apps directory.
You don't need to load the tags in your admin/index.html file, the context is
passed to it already. Should only load it if you're using other custom
filters or tags from the same app.
Your html for admin/index.html should be:
{% for cat in categories %}
{{ cat.name }}
{% endfor %}
In the html/template file that is using the nav_categorieslist tag, it should
look like this:
{% load categories %}
{% nav_categorylist %}
I normally put my load tags at the top of the template file.
If you set the TEMPLATE_LOADERS setting to include
'django.template.loaders.app_directories.load_template_source',
You can put the template tags html file in your app directory also, i.e.
app/templates/admin/index.html; I do it this way to seperate the html from
template tags from the rest of the html.
