Referring to an instance of a dash application, uniquely identified by a slug, will use the persisted representation of that app along with its initial state.
Each time this page is reloaded, the application will revert to its stored initial state. This initial state is persisted in a standard Django model.
It is also possible to specify initial arguments in the template. These override the values specifed in the code defining the app, and also take priority over any stored state.
{% load plotly_dash %}
{% plotly_app slug="simpleexample-1" ratio=0.1 %}
{% plotly_app name="simpleexample-1" initial_arguments='{"dropdown-color": {"value": "green"}}' %}
