Hello, Creating a custom multi-level stepper with a progress bar in Angular 12 can be an intricate task, especially if you also want to include sub-steppers within each step. However, Angular’s powerful data binding and component-based architecture can make this task manageable. You can achieve this by breaking down the problem into smaller, manageable components and then assembling them together. Step 1: Create the Stepper Component First, you will need to create a stepper component that can handle both primary steps and sub-steps. Create a New Component : Use Angular CLI to generate a new component: ng generate component multi-level-stepper Define the Steps : In your stepper component, define the data structure to hold the steps and sub-steps. For example: export interface Step { title: string; completed: boolean; subSteps: SubStep[]; } export interface SubStep { title: string; completed: boolean; } Template for Stepper : In your component’s template, iterate over the steps and sub-steps to display them. Use Angular Material or similar UI libraries for a polished look, or create custom CSS styles.

Step 2: Create the Progress Bar For the progress bar, you can use Angular Material’s ProgressBar module or create a custom progress bar. Install Angular Material (if not already installed): ng add @angular/material Use Material Progress Bar : Import MatProgressBarModule in your module and use in your stepper component template. Calculate Progress : Implement a method in your stepper component to calculate the progress based on the completion of steps and sub-steps. calculateProgress(): number { // Implement logic to calculate progress } Step 3: Implement Sub-Stepper Logic Within each primary step, you can have sub-steps. You need to manage the state of each sub-step and update the main step’s state accordingly. Manage Sub-Step State : Update the completion state of each sub-step based on user interaction. Update Main Step State : When all sub-steps of a main step are completed, update the main step’s completion state. Step 4: Styling Use CSS to style your stepper and progress bar. You can customize the styles as per your design requirements. .step { /* styles for step */ } .step.completed { /* styles for completed step */ } .sub-steps { /* styles for sub-steps */ } .sub-steps .completed { /* styles for completed sub-step */ } Finally, integrate the stepper component into your application, and test its functionality thoroughly. Make sure the progress bar updates accurately as steps and sub-steps are completed. This high-level guide gives you a starting point for implementing a multi-level stepper with a progress bar in Angular. Depending on your specific requirements and the complexity of your application, you might need to adjust and extend this basic implementation. Best, Bobby
