# `MishkaGervaz.Form.Web.State.StepBuilder`
[🔗](https://github.com/mishka-group/mishka_gervaz/blob/v0.0.1-alpha.3/lib/mishka_gervaz/form/web/state/step_builder.ex#L1)

Builds wizard/tabs step configuration from DSL.

Steps define the multi-step form flow. Each step references groups,
has optional validation actions, and lifecycle callbacks.

## Overridable Functions

- `build/2` - Build steps from config and resource
- `initial_step/1` - Determine the initial step
- `initial_step_states/1` - Build initial step states map
- `step_valid?/2` - Check if a step is valid/complete

## User Override

    defmodule MyApp.Form.StepBuilder do
      use MishkaGervaz.Form.Web.State.StepBuilder

      def initial_step(steps) do
        # Always start at the second step
        case steps do
          [_, second | _] -> second.name
          _ -> super(steps)
        end
      end
    end

See `MishkaGervaz.Form.Web.State`,
`MishkaGervaz.Form.Entities.Step`, and the sibling builders
