It'd be nice if could pass attrs from parent to child at compose time

[neilmcguigan]

Say I want a generic container component that can dynamically set args on declared child components

like this:

<Parent>
  <Child {someAttrsFromParent} />
  <Child />
</Parent>

You can do this w Jinja macros (awkwardly):

{% call(kwargs) parent() %}
  {{ child(foo=1, **kwargs) }}
  {{ child(foo=2, **kwargs) }}
{% endcall %}

where parent looks like this:

{% macro parent() %}
...
{{  caller( dict(bar=2) ) }}
...
{% endmacro %}

You can! But it's barely mentioned in the docs :( (https://jinjax.scaletti.dev/guide/extra/#attrs-methods).

<Parent>
  <Child __attrs={attrs} />
  <Child />
</Parent>

1. attrs are the parent attrs
2. __attrs begins with two underscores

If you only want to pass some arguments (and you know which ones), you can do it like any other value (attrs is similar to a dict)

<Parent>
  <Child title={attrs.get('title') or 'Hello'} />
  <Child />
</Parent>

Is something like a React context provider possible?

{# def model#}
<Datagrid mode={model}>
  <Field name="id">
  <Field name="grid">
</Datagrid>

Where model is an sqlmodel that each Field wants to introspect to find out it's datatype so it can render differently. And the Datagrid component somehow internally handles passing the model to each of it's children.
