Add load priority

[Nano1237]

Is your feature request related to a problem? Please describe.
If several components build on one another, they must be executed in the correct order.

Describe the solution you'd like
I was either thinking of a simple number indicating the priority, or possibly a queue of components.

Additional context
Things like EventListener (e.g. resize) must also be taken into account during implementation.
If a component omits a height during initialization that is set by another component, this sequence must also be observed for other triggers.
