When building large Django applications, one problem slowly becomes painful:

sidebar management

Enter fullscreen mode

Exit fullscreen mode

Especially in modular systems like:

HRMS

CRM

ERP

Admin panels

Multi-app dashboards

At first, updating the sidebar feels simple.

But once your project grows to:

10+ apps

multiple contributors

role-based permissions

dynamic navigation

HTMX interactions

your sidebar.html quickly becomes a maintenance nightmare.

The Problem I Faced

In my Django CRM project, every new app required updating:

sidebar.html sub_sidebar.html

Enter fullscreen mode

Exit fullscreen mode

Example:

<li> <a href= "/accounts/" > Accounts </a> </li>

<li> <a href= "/contacts/" > Contacts </a> </li>

Enter fullscreen mode

Exit fullscreen mode

This caused several problems:

Every contributor had to modify core sidebar templates

Frequent Git merge conflicts

Sidebar logic became centralized and difficult to maintain

Permission handling became repetitive

Adding new apps required…
